1. Overview
The TK-2360 is a VHF portable transceiver designed to
Operate in the frequency range of 136~174MHz. The unit
consists of a receiver, transmitter, phase-locked loop (PLL)
frequency synthesizer, base band parts, power supply and
control circuits.
2. Frequency Configuration
The receiver utilizes double conversion. The first IF is
49.95MHz and the second IF is 450kHz. The first Local os-
cillator is supplied from the PLL circuit.
The PLL circuit in the transmitter generates the neces-
sary frequencies.

3-1. Front End (RF Amplifier) Circuit
The signal coming from the antenna passes through the
transmit/receive switching diode circuit (D201, D202, D203
and D204) and a BPF (L418 and L419), and is then amplified
by the RF amplifier (Q407).
The resulting signal passes through a BPF (L414 and
L416) and goes to the mixer. These BPFs are adjusted by
variable capacitors (D404, D405, D407 and D408). The input
voltage to the variable capacitor is a regulated voltage out-
put from the DC amplifier (IC811).
3-2. First Mixer
The signal from the front end is mixed with the first local
oscillator signal generated in the PLL circuit by Q406 to pro-
duce a first IF frequency of 49.95 MHz.
The resulting signal passes through the XF401 MCF to
cut the adjacent spurious and provide the optimum charac-
teristics, such as adjacent frequency selectivity.

TK-2360

3-3. IF Amplifier Circuit
The first IF signal is passed through a four-pole mono-
lithic crystal filter (XF401) to remove the adjacent channel
signal. The filtered first IF signal is amplified by the first IF
amplifier (Q405) and is then applied to the IF system IC
(IC401).
The IF system IC provides a second mixer, limiting ampli-
fier, quadrature detector and RSSI (Received Signal Strength
Indicator). The second mixer mixes the first IF signal with
the 50.4MHz signal of the second local oscillator output
(Q403) and produces the second IF signal of 450kHz.
The second IF signal is passed through the ceramic filter
(Wide: CF402, Narrow: CF401) to remove the adjacent chan-
nel signal. The filtered second IF signal is amplified by the
limiting amplifier and demodulated by the quadrature detec-
tor with the ceramic discriminator (CD401). The demodu-
lated signal is routed to the audio circuit.
3-4. Wide/Narrow Switching Circuit
Wide and Narrow settings can be made for each channel
by switching the ceramic filters CF402 (Wide), CF401 (Nar-
row). The Wide and Narrow switching data is output from
IC809.
D401 and D402 are switched to ceramic filters when a
Wide/Narrow level is selected.

3-5. Audio Amplifier Circuit
The demodulated signal from IC401 is sent to an AF am-
plifier through IC812, and is routed to an audio power ampli-
fier (IC815) where it is amplified and output to the speaker.
3-6. Squelch Circuit
Part of the AF signal from the IC401 enters the FM IC
(IC401) again, and the noise component is amplified and
rectified by a filter and an amplifier to produce a DC voltage
corresponding to the noise level.
The DC signal from the FM IC goes to the analog port of
the MCU (IC809). IC809 determines whether or not to out-
put sounds from the speaker by checking if the input volt-
age is higher or lower than the preset value.
To output sounds from the speaker, IC809 sends a high
signal to the AFSW line and turns IC815 on through Q813,
Q814, Q818 and Q819.
4. Transmitter System
4-1. Microphone Amplifier Circuit
The signal from the microphone is limited by the AGC
circuit, which is composed of D807, 808, Q810, Q811 and
the mute switch (Q809). IC812 is composed of a high-pass
filter, low-pass filter and pre-emphasis/IDC circuit.
The signal from the microphone and the low speed data
from the MCU (IC809) enter the Audio processor IC (IC812)
and pass through each path and are mixed inside the IC.
The output signal from the audio processor goes to
the VCO modulation input. The other output signal passes
through the amplifier (IC3) and goes to the TCXO modula-
tion input.

4-2. Driver and Final Amplifier Circuit
The signal from the T/R switch (D18 is on) is amplified by
the RF AMP (Q201) and pre-drive amplifier (Q203) to 50mW.
The output of the pre-drive amplifier is amplified by the
drive amplifier (Q204) and the RF final amplifier (Q205) to
5.0W (1W when the power is low).
The drive amplifier and the RF final amplifier consist of
two MOS FET stages.
The output of the RF final amplifier is then passed
through the harmonic filter (LPF) and antenna switch (D201
and D202) and is applied to the antenna terminal.
4-3. APC Circuit
The APC circuit always monitors the current flowing
through the drive amplifier (Q204) and the RF power ampli-
fier (Q205) and keeps a constant current. The voltage drop
at R307, R309 and R310 is caused by the current flowing
through the RF final amplifier. This voltage is applied to the
differential amplifier IC301 (1/2).
IC301 (2/2) compares the output voltage of IC301 (1/2)
with the reference voltage from IC811. The output of IC301
(2/2) controls the VG of the RF power amplifier and the drive
amplifier to make both voltages the same.
The change of power high/low is carried out by the
change of the reference voltage.
CIRCUIT DESCRIPTION
Fig. 5 Driver and final amplifier and ACP circuit
5. Frequency Synthesizer Unit
5-1. Frequency synthesizer
The frequency synthesizer consists of the TCXO (X1),
VCO, PLL-IC (IC1), and buffer amplifiers.
The TCXO generates 16.8MHz. The frequency stability
is 1.5ppm within the temperature range of –30°C to +60°C.
The frequency tuning and modulation of the TCXO are done
to apply voltage to pin 1 of the TCXO. The output of the
TCXO is applied to pin 10 of PLL-IC.
The VCO consists of 2 VCOs and covers a dual range of
185.95~223.95MHz for providing the first local signal for
reception. The operating frequency is generated by Q5 in
transmitting mode and Q4 in receiving mode. The oscillation
frequency is controlled by applying the VCO control voltage,
obtained from the phase comparator (IC1) to the variable ca-
pacitance diodes (D6, D7, D8, and D9 in transmitting mode
and D3 and D5 in receiving mode)
The TX pin of IC809 goes “high” in transmitting mode,
causing Q7 and Q4 to turn off, and Q5 turn on. The TX pin
goes “low” in receiving mode.
The output from Q4 and Q5 are amplified by a buffer am-
plifier (Q8) and Q2, and then sent to the PLL-IC.
The PLL-IC consists of a prescaler, reference divider,
phase comparator, and charge pump. The input signal from
pin 10 and 17 of the PLL-IC is divided down and compared
at the phase comparator. The pulsed output signal of the
phase comparator is applied to the charge pump and trans-
formed into a DC signal in the loop filter (LPF). The DC sig-
nal is applied to the CV of the VCO and locked to keep the
VCO frequency constant.
PLL data is output from PLLLE (pin 46), PLLCLK (pin 47),
and PLLDAT (pin 45) of the MCU (IC809). The data is input
to the PLL-IC when the channel is changed or transmission
is changed to reception and vice versa. The PLL lock condi-
tion is always monitored by pin 48 (PLLLD) of the MCU.
When the PLL is unlocked, PLLLD goes low.

6. Control Circuit
The control consists of the MCU (IC809) and its peripher-
al circuits. It controls the TX-RX unit. IC809 mainly performs
the following;
1) Switching between transmission and reception by PTT
signal input.
2) Reading channel information, frequency, and program
data from the memory circuit.
3) Sending frequency program data to the PLL.
4) Controlling squelch on/off via the DC voltage from the
squelch circuit.
5) Controlling the audio mute circuit via the decode data in-
put.
6) Transmitting tone and encode data.
6-1. Frequency Shift Circuit
The MCU (IC809) operates at a clock frequency of
12.0MHz. This oscillator has a circuit that shifts the frequen-
cy via Beat shift switch (Q806, Q807).
A beat sound may be able to be evaded form generation
if “Beat Shift“ is set to ON when it is generated in the in-
ternal spurious transmission modulated sound of the trans-
ceiver.

The battery voltage is monitored by the MCU (IC809 pin
86: BATT). When the battery voltage falls below the volt-
age set by the Low Battery Warning adjustment, the red
LED blinks, notifying the operator that it is time to replace
the battery (when the always option (default setting) under
the Battery Warning function in the FPU is selected). If the
battery voltage falls bellow 5.9V, the transceiver does not
transmit and the warning tone beeps while the PTT switch
is pressed.
Low battery warning Battery status
The red LED blinks during trans-
mission.
The battery voltage is low but
the transceiver is still usable.
The red LED blinks and the
warning tone beeps while the
PTT switch is pressed.
The battery voltage is lowand

6-4. Battery Type Detection
The transceiver automatically detects the battery type,
measuring the resistance between the S-terminal and +ter-
minal on the battery pack and changes the supplied voltage
to the S-terminal as below. The MCU then detects the bat-
tery type.

7-1. Encode
■Low-speed data (QT, DQT)
Low-speed data is output from pin24 of the MCU. The
signal passes through the low pass CR filter, and goes to
the audio processor (IC812). The signal is mixed with the
audio signal and goes to the VCO and TCXO (X1) modulation
input after passing through the D/A converter inside the au-
dio processor (IC812) for BAL adjustment.

■High-speed data (2-tone, DTMF)
High-speed data (HDS) is output from pin 1 of the MCU.
HDS deviation made by an adjustment in the MCU is passed
through the low pass CR filter and then applied to the audio
processor (IC812).
The signal is mixed with the audio signal and goes to the
VCO and TCXO. The side tone is output from Pin 2 of the
MCU. The signal passes through low pass CR filter and D/A
converter, and goes to the audio power amplifier. The level
is controlled by the MCU.
■MSK
The MSK signal is generated in the audio processor
(IC812). The signal passes through the D/A converter (inside
the audio processor: IC812) and is routed to the VCO. When
encoding the MSK, the microphone input signal is muted.
7-2. Dceode
■QT/DQT
The output signal from the IF IC (IC401) enters the MCU
(IC809) through IC812. IC809 determines whether or not
the QT or DQT matches the preset value, and controls the
AFSW and speaker output sounds according to the squelch
results.
■2-tone
Part of the received AF signal output from the IF IC (IC401)
passes through an audio processor (IC812) goes to the oth-
er AF amplifier IC808 and 816, is compared, and then goes
to IC809. IC809 checks whether or not the 2-tone data is
necessary. If it matches, IC809 carries out a specified opera-
tion, such as turning the speaker on.
■MSK (Fleet Sync)
The MSK input signal from the IF IC (IC401) goes to
IC812. The decoded information is then processed by the
MCU.
■DTMF
The DTMF input signal from the IF IC (IC401) goes to
IC812. The decoded information is then processed by the
MCU.
8. Power Supply
There are five 5V power supplies and three 3.3V power
supplies: 50M, 50V, 50C, 50R, 50T, 33M, 33MSC and 33BC.
50M and 33M are always output while the power is on.
33MS is always output, but turns off when the power is
turned off, to prevent malfunction of the MCU.
50C is a common 5V and is output when SAVE is not set
to ON.
50R is 5V for reception and output during reception.
50T is 5V for transmission and output during transmis-
sion.
50V is 5V for the SP/MIC connector.
33B is 3.3V for the audio processor (IC812).
