THEORY OF OPERATION
This PLL - controlled VHF marine transceiver provides an accurate and stable multi-channel operation.
The transceiver consists of 8 main sections:
 Transmitter
 Receiver
 Low voltage detection
 Voice recorder
 Local oscillator PLL (Phase Loc Loop) Circuit
 Memory bac up
 Bluetooth
 ATIS(Automatic Transmitter Identification System) Only for HH475Eu
 Transmitter
The audio is picked up from the internal M C, the audio signal is then amplified by Audio Amplifier, U4
LM324 (2/4), U4 (3/4) and filtered by a low pass filter U4 (4/4). The audio is adjusted with VR2 to obtain a
suitable Audio frequency response, and then modulated with the carrier by VCO, through Varicap (D11).
The modulated signal output from the VCO is pre-amplified by Q5, Q4 and Q3. Then it is amplified by Q12,
Q6 .The amplified signal then passes through a low -pass filter network which consists of C72, L8, C66,
C15, L6, C4 filters out spurious emission, and the antenna switching circuit, D1, D2. The signal is filtered
by another low-pass filter circuit which consists of C16, L2, C62, C12, L1, C5, C1. These low pass filters
are necessary to suppress the second and third harmonics. The signal is then fed into the antenna input
and radiated out.
TX current is converted into a voltage signal, that signal fed into U2 LM2904 (2/2) for sampling. U2 is the
Automatic power control (APC) circuit.
When the unit is transmitting, the audio signal is added to the TX VCO Varicap D11. The capacitance of
D11 is varied following the audio signal and when mixed with the carrier to form the modulated signal.
 Receiver
The receiver uses a double frequency super-heterodyne circuit. The first mmediate Frequency ( F) is 21.4
MHz and the second is 450 kHz.
The RF signal is received by the antenna, and passes through a low-pass filter network C1, L1, C5, C12,
L2, C62, C16, C20, L7, C67 to filter out the unwanted signals, the antenna switching circuit D1, D2
switching circuit to receive. The received RF signal is sent to a SAW filter F1 to filter out-of-band signals.
The RF amplifier Q7 amplifies signals within the range of the frequency coverage and passes though
another saw filter F2 to further filter out-of-band signals. The RF signal then is mixed with the local
oscillation frequency by the mixer Q8. A first F ( mmediate Frequency) 21.4 MHz is produced. The F is
passed through a pair of crystal filter F3 (1/2), F4 (2/2) to further filter other unwanted signals. The first F
4

then is amplified by Q2 and the F amplifier U1 (BA4116). U1 is a integrated RF amplifier which consists
of a local oscillator, a demodulator, a second mixer, squelch control circuit, and RF amplifier. The 21.4
MHz F then is mixed here with second mixer and converted into 2nd mmediate Frequency ( F) 450 kHz.
The 2nd F passes through a ceramic filter F5 to filter out the residue unwanted signal at pin 5 of U1
(BA4116) output this final F signal and the Audio signal is output at pin 9 of U1 (BA4116).
The audio signal is fed through a volume control VR3 and finally amplified by Audio amplifier U11
(NJM2070) and heard in the speaker.
The squelch control is also controlled by U1 (BA4116). The second F passes through U1 (BA4116)
internal squelch control R90, C141, C142 form as a squelch amplifier. The ceramic filter produces a
squelch signal (RF noise). Pin 14 of U1 sends the digital squelch control signal to the CPU mute the audio
speaker path. Pin 12 of U1 output a RSS level to the CPU.
 Low Voltage Detection
The battery voltage, divided by R148, R149 is input to U7 Pin 11 for voltage level sample.
 Voice recorder
Voice recorder consists of U5(4/4) LM324,U9(AT4SDBD41B)and MCU U7.Voice source from AF via
U5(4/4) LM324 amplifies then pass to MCU U7 pin 13,or voice signal from M C via U4(1/4,2/4,3/4) then
pass to MCU U14,they will be transformed to voice data up to 20 seconds, U9(AT4SDBD41B) stores these
voice data. When recorder play, the voice come out form MCU U7 Pin43. Then pass to U4(4/4), after that
pass to U11(NJM2070) to amplify the recorder voice signal.
 PLL (Phase Loc Loop) Circuit:
The receiver and transmitter both share the same PLL (Phase Lock Loop) Circuit to produce the carrier or
the receive frequency. The local oscillator consists of a fundamental frequency oscillator X1 20.95MHz and
U6 (KB8825). A phase Lock Loop (PLL) U6 (KB8825), TX VCO Q14 and RX VCO Q13. The fundamental
frequency is frequency divided by U6 and a 12.5 kHz signal is produced. When the VCO frequency
applied to and frequency divided by U6 produces a frequency comparable to 12.5 kHz, PLL will control the
VCO. When these two frequencies are matched, a constant control voltage is output from PLL to lock
VCO in desired frequency. The PLL also will output a lock indication to MCU to indicate the PLL is in
frequency lock state.
 Memory Bac up
U9 is an EEPROM AT4SDB41B which acts as a memory backup for the working channel code and the
system parameters. Every time when the unit is switched on, the MCU will reset the system, clear the
RAM, and recall in the memory from the EEPROM to refresh the RAM in CPU U7.
 Bluetooth
Bluetooth circuit consists of U13(BT_MODULE)and CPU U7.When Bluetooth transmitting the voice from
U13 Pin7 and 5 input, then via U7 controls and U13 transforms to Bluetooth RF signal then radiates out by
5

BT-ANT; When Bluetooth receiving, Bluetooth RF signal comes from BT-ANT via U7 and U13 then
changes to voice signal from U13 Pin 4 output.
 ATIS(Automatic Transmitter Identification System) ONLY for HH475EU
AT S circuit consists of U5(1/4),U4(4/4) and CPU U7, when receiving the AF signal from U1 Pin 9 via
U5(1/4) then pass to CPU U7 Pin 43, when transmitting A TS PWM signal form U7 Pin 45 output then via
U4(4/4) pass to TX VCO Varicap D11 then mixes with the carrier to form the modulated signal.
