THEORY OF OPERATION
This PLL - controlled VHF marine transceiver provides an accurate and stable multi-channel operation.
The transceiver consists of 6 main sections:
z Transmitter
z Receiver
z Low voltage detection
z Local oscillator PLL (Phase Lock Loop) Circuit
z Memory backup
z ATIS(Automatic Transmitter Identification System)
z Transmitter
The audio is picked up from the internal MIC, 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.
z Receiver
The receiver uses a double frequency super-heterodyne circuit. The first Immediate Frequency (IF) 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 IF (Immediate Frequency) 21.4 MHz is produced.
The IF is passed through a pair of crystal filter F3 (1/2), F4 (2/2) to further filter other unwanted
signals. The first IF then is amplified by Q2 and the IF amplifier U1 (BA4116). U1 is a integrated RF
amplifier which consists of a local oscillator, a demodulator, a second mixer, squelch control circuit,
4
and RF amplifier. The 21.4 MHz IF then is mixed here with second mixer and converted into 2nd
Immediate Frequency (IF) 450 kHz. The 2nd IF passes through a ceramic filter F5 to filter out the
residue unwanted signal at pin 5 of U1 (BA4116) output this final IF 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 IF 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 RSSI level to the CPU.
z Low Voltage Detection
The battery voltage, divided by R148, R149 is input to U7 Pin 11 for voltage level sample.
z PLL (Phase Lock 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 X2
20.95MHz and U6 (GP214D). 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.
z Memory Backup
U14 is an EEPROM AT24C16 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.
z ATIS(Automatic Transmitter Identification System) only for EU
ATIS 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 AITS 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.
