Table 1 Comparison of TM-221A, TM-221E and TM-221ES
Frequeny configuration
The TM-221A/E/ES utilize a PLL synthesizer system
incorporating a digital VFO. (See Fig. 1.) The channel
step can be selected as 5, 10, 12.5 (T,W), 15, 20, or 25kHz.’
The receiver operates as a double conversion system. Re-
ceived signals are mixed with the first local oscillator
(133.305~137,300MHz (K,M), 133,300~135.295MHz
(T,W)) to produce the first intermediate frequency of
10,.695MHz (K,M), 10.7MHz (T,W). The first intermediate
frequency is mixed with the second local oscillator (10.24
MHz (K,M), 10.245MHz (T,W)) to produce the second
intermediate frequency of 455kHz.
The transmitter system consists of a PLL circuit in-
corporating a direct oscillator and direct divider. The
output is amplified by a linear amplifier prior to being
transmission.

Receiver system
@ General
Incoming signals from the antenna pass through a low-
pass filter in the Transmitter Final unit and a diode trans-
mit/receive switch, then enter the receiver front end.
After passing through two antenna coils the signals are
amplified by a GaAs (galium arsenide) FET (Q1
3SK184(S). Undesired signals are removed by 3 tuning
coils (L19~L21 : K,M) or a 3-pole helical resonator (L3 :
TW). The resulting signal is applied to the first mixer
Q2 : 3SK131(V12), which employs an N channel MOS FET
to obtain good 2-signal characteristics. In the first mixer
(Q2) the signal is mixed with the first local oscillator
from the PLL system to produce the first IF signal of
10.695MHz (K,M), 10.7MHz (T,W). Interfering Adjacent
channel interference is removed from the first IF signal
by a two-stage monolithic crystal filter (MCF) (L6).

CIRCUIT DESCRIPTION
Transmitter system
@ General
in the transmitter system the desired frequency is pro-
duced directly by an oscillator. Frequency modulation is
obtained directly thru the use of a varactor diode.
@ Modulation circuit
Audio signals from the microphone are applied to a
three-stage operational amplifier which adds preemphasis,
performs amplification and limiting, and includes a splatter
filter to remove undesired high-frequency components.
After amplification by the operational amplifier, part of
the audio signal is applied to the microphone check circuit
used in the low-power mode.
In the FM modulation circuit, the frequency of the
VCO is directly modulated by a varactor diode.

TX-RX UNIT
TO FINAL UNIT
@ Preamplifier stage circuit
The output from the VCO enters the linear amplifier,
which is capable of high-quality signal amplification
because it operates entirely in linear mode. APC, (Auto-
matic Power Control) is performed by controlling the
collector voltage of the 3 stage final preamplifier stage.
@ Power amplifier circuit
The drive signal is applied to the power module and
amplified to the required level. In the model TM-221A/
ES heat is dissipated efficiently by a large mechanically
strong heatsink.
@ APC and SWR protection circuits
Fig. 3 shows the basic ALC (Automatic Level Control)
and SWR (Standing Wave Ratio) protection circuits. The
SWR protection circuit incorporates a CM coupler that
detects any reflected power caused by mismatching of the
antenna. After detection and amplification, this circuit
acts to lower the output contro! voltage, which protects
the power module by reducing the gain. The automatic
power control (APC) circuit incorporates a diode that is
used to detect a portion of the output from the power
module. The detected signal is amplified and is then used
to control the power control voltage. The control voltage
is inversely proportional to the output, so a constant
output level is maintained.

CIRCUIT DESCRIPTION
PLL synthesizer
Fig. 4 is the PLL system block diagram. The trans-
mitter and receiver systems of the TM-221A/E/ES have
independent VCOs and PLLs, but share a common low-
pass filter.
The VCOs are configured as subunits. This construc-
tion minimizes outside influence and improves frequency
stability.

CIRCUIT DESCRIPTION
® Unlock detector circuit
Whenever the PLL is unlocked, pin 10 of the PLL IC goes
high (“H") (5.5V), turning off Q15 so that Q1 and Q2
in the module unit (drive unit) turn OFF. The result is
that during receive Q17 is OFF, and during transmit
Q4 and Q5 in the module unit are OFF, This halts trans-
mit, preventing unwanted radiation from the antenna.

@ Alert and electronic volume contro! output (when
optional remote controller is connected)
The alert and electronic volume contro! outputs are
provided by pins P92 (CK), P91 (DT), and P21 (ST) of
the microprocessor to the 8-bit shift register (1C3) in
the TX-RX unit. P92 (CK) and P91 (DT) are also used for
the PLL data. Fig. 13 shows the data transfer format.

@ Tone output
The outputs from pins P40 to P43 and P50 to P53
of the microprocessor are applied to a ladder resistance
network (IC4) which converts these signals into an analog
waveform with 38 possible tone frequencies combinations

CIRCUIT DESCRIPTION
@ S-meter and RF meter input
The analog voltage of the S-meter is applied to pin
PTHOO of the microprocessor, and the analog voitage of
the RF meter to pin PTHO1. After 4-bit (16-step) analog-
to-digital conversion, the resulting signal is sent to the
display.
@ Busy input
When squelch is ON and an input signal is present, a
tow input lights the busy indicator.
@ CTCSS unit (option : TM-221A only) input and output
The microprocessor sends data from pins P30, P31, and
P61 to the CTCSS unit. Fig. 16 shows the data transfer
format. Fig. 17 shows the data configuration. When a tone
is detected from the CTCSS unit, a ‘’'H”’ is applied to pin
P32 of the microprocessor to open the squelch.
