TEKCOM Industries Limited Page 1 of 6 THEORY OF OPERATION VHF7100/VHF7000 (For NAVMAN) November 28, 2003 This PLL controlled VHF marine mobile transceiver provides an accurate and stable multi-channel operation. The transceiver consists of 12 main sections Transmitting stage !" Receiving stage !" Local oscillator PLL (Phase Lock Loop) Circuit !" Memory backup !" Low voltage detection !" Large LCD !" Local/distance circuit !" 2nd receiver. (only VHF7100EC) !" wx alert circuit [only VHF7100USA] !" PC program !" DSC Feature [only VHF7000ROW without] !" GPS Message [only VHF7000ROW without] !" ATIS Feature. (only VHF7100EC) !" Transmitter Stage The audio is picked up from the internal Mic. The audio signal is then amplified by Audio Amplifier, IC205C [NJM3403AM], IC205 B [NJM3403AM] and filtered by a low pass filter IC10C [NJM3403AM]), IC10D [NJM3403AM]). The audio that is adjusted by VR3 to obtain a suitable RF frequency-deviation, modulates the carrier of VCO, through Varicap (VD302). The modulated signal output from the VCO is pre-amplified by Q2, and IC1 (RA35H1516M-01). When the supply voltage is 13.8V, this signal will be amplified up to 1W or 25W. The signal is filtered by low-pass filter circuit of which consists of L1, L2, L4, C1, C2, C3, C5, C6. C14, C47 and C62.These low pass filters are necessary to suppress the second and the third harmonics as higher. The signal is then fed into the antenna input and radiated out. The signal is also fed into another path consisting of C9, C10, D3, D4 for sampling, and is converted into a direct current voltage for the Automatic Power Control (APC) circuit IC12 (NJM2904M) Q5, Q14, Q15,Q24 to control the voltage of IC1 Pin 2 to maintain the output power stability. Q15 is used control Hi/Lo power When the unit is transmitting, the channel control voltage is added to the TX VCO varicap VD306. The capacitance of VD302 is varied following the audio signal, therefore the carrier is modulated to form the modulated signal. !" Receiver The receiver uses a double frequency super-heterodyne circuit. The first Immediate Frequency (IF) is 21.4 MHz and the second is 455 KHz. The RF signal is received by the antenna, and passes through a low-pass filter network L1, L2, L3, L9, C1, C2, C3, C5, C6. C14, C47 and C62 to filter out unwanted signal. the received RF signal then passes through a high RF transformer L10 and is amplified by RF amplifier Q9. L11, L12, L13, C15, C18, C20 form the band pass filter. The RF signal then is mixed with the local oscillation frequency by the mixer
TEKCOM Industries Limited Page 2 of 6 D22, D23. The first IF (Immediate Frequency) 21.4 MHz is produced. This IF is passed through a coil T2 and a pair of crystal filter F1, F2 to further filter out other unwanted signals. The first IF then is amplified by Q11 and the IF amplifier IC7 (BA4116FN). (IC7 is an integrated IF amplifier which consists of a local oscillator, a demodulator, a second mixer, squelch control circuit, and IF amplifier). The 21.4 MHz IF then is mixed here with second mixer and converted into 2nd Immediate Frequency (IF) 455 kHz. The 2nd IF passes through a ceramic filter F4 to filter out the residue unwanted signal at pin 5 of IC7 (BA4416FN) output this final IF signal and The demodulated AF signal is output at pin 9 of IC7 (BA4416FN). The demodulated AF signal is amplified by IC8B. the amplified audio then passes through a volume control VR201 through de-emphasis circuit feeding IC10A, IC10B.and finally amplified by Audio amplifier IC11 (LA4629) and heard in the speaker. The squelch control signal also produced by IC7 (BA4116FN), the rectified noise signal is output by Pin 14 of the IC7 then signal is amplified by IC8A. Pass through the network by composition of R45 R38 R44 and C171 sends the digital squelch control signal to the MCU to mute the audio speaker path and to indicate the RX station on LCD. R214.R217 and VR203 form a variable resistor, which correspond to the squelch level. !" Local oscillator PLL (Phase Lock Loop) Circuit: The receiver and transmitter both share the same PLL (Phase Lock Loop) Circuitry to produce the carrier frequency or the receiver local oscillation frequency. The local oscillator consists of a fundamental frequency oscillator Q301 and A phase Lock Loop (PLL) IC16 (TB31202) When Rx 5Vvoltage is supply, the VCO will produce receiver local oscillator frequency. The high stability frequency is determined by crystal X2 (20.950 MHz) and as the PLL reference oscillator. This signal is frequency-divided by IC16 and a 12.5 kHz signal is produced. When the VCO frequency applied to IC16 pin1 and frequency-divided by IC2 produces a frequency comparable to 12.5 kHz, PLL IC pin 3 will output a PD voltage to control the VCO. When these two frequencies are matched, a constant control voltage is output from PLL to lock VCO in desired frequency. Otherwise the PLL IC pin 4 will also output a unlock indication to MCU to indicate that the PLL is in the frequency unlock state. !" Memory Backup IC201 is an EEPROM AT24C64, 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 the memory from the EEPROM to refresh the RAM in MCU IC203. !" Low Voltage Detection The battery voltage divided byR250 and R251 through R254 is input to IC203 for voltage level detection. If the battery voltage drops below 9.5 V, LCD will indicate the battery is in low state. !" Local/distance circuit Local/distance circuits are composed of Q16,R195,R94,C125.L17,D17,R93. When local SW is on high level, receiver sensitive is high otherwise is on low. !" Wx alert circuit The 1050Hz tone of receiver through IC6A composed band-pass filter and IC6B amplifier form square wave signal. To fed IC203 pin 97produce weather alert. !" Large LCD All message through series bus from MCU to display driver IC204 and will be displayed through a 1.5 ′′ 1 ′′× 1 ′′ in 4 × …

Tampering with the radiotelephone may upset the alignment and lower its performance. Test Equipment Required: !" Regulated DC power supply, 15V,7A !" Audio signal generator,10Hz~3kHz !" Digital multimeter !" Deviation meter !" Frequency counter,0~500MHz high impedance !" Oscilloscope !" RF power meter, ≥ 30W !" High frequency standard generator,>500MHz !" Tracking generator,>500MHz !" Distortion analyzer !" Audio level meter !" T-coupler !" Alignment drivers, etc. ADJUSTMENT PROCEDURE Step Item Adjustment Procedure 1 TX Frequency VC2 Adjust VC2 to obtain demanded TX frequency. 2 TX Power Hi VR5 Adjust VR5 to obtain demanded TX power 23 ± 2W. 3 TX Power Lo VR6 Adjust VR6 to obtain demanded TX power 0.8 ± 0.1 W. 4 TX. Dev. VR3 1. Inject an audio frequency (AF) -20dBm. 2. Adjust VR3 to obtain maximum TX deviation ≤ 5kHz. 3.
