FCC ID: K6610344140 IC ID: 511B-10344140 Circuit Description 1/3 Vertex Standard Co., Ltd. VX-5500U Circuit Description Reception and transmission are switched by “ RX ” and ” TX ” lines from the microprocessor unit (MPU). The receiver uses double-conversion super-heterodyne circuitry, with a 43.95MHz 1st IF and 450 kHz 2nd IF. The 1st LO, produced by a PLL synthesizer, yields the 43.95MHz 1st IF. The 2nd LO uses a 43.5 MHz (43.95 MHz-450 kHz) signal generated by a crystal oscillator. The 2nd mixer and other circuits use a custom IC to convert and amplify the 2nd IF, and detect FM to obtain demodulated signals. During transmit, the PLL synthesizer oscillates at the desired frequency directly, for amplification to obtain RF power output. During transmit, voice modulation and CTCSS (or DCS) modulation are applied to this synthesizer. Transceiver functions, such as Tx/Rx control, PLL synthesizer settings, and channel programming, are controlled using the MPU. Receiver Incoming RF signals from the antenna connector are delivered to the MAIN Unit, and pass through a low-pass filter (LPF) antenna switching network consisting of coils L1002, L1004, L1006, L1008 and L1001, capacitors C1017, C1022, C1028, C1039, C1046 and C1001, and antenna switching diodes D1047 and D1049 for delivery to the receiver front end. Signals within the frequency range of the transceiver are then passed through a varactor-tuned band-pass filter consisting of L1007, L1010 before RF amplification by Q1018. The amplified RF is then band-pass filtered again by varactor-tuned resonators L1023, L1027 and buffer amplifier by Q1030 to ensure pure in-band input to 1st mixer Q1188. Buffered output from the VCO Unit is amplified by Q1032 and low-pass filtered by L1036 / L1040 and C1210 / C1216 / C1227, to provide a pure 1st local signal between 406.05 and 446.05 MHz to the 1st mixer. The 43.95MHz 1st mixer product then passes through dual monolithic crystal filters XF1001 and XF1002 (12 kHz BW)/ XF1003 and XF1004 (7kHz BW) and is amplified by Q1041 and delivered to the input of the FM IF subsystem IC Q1034. This IC contains the 2nd mixer, 2nd local oscillator, limiter amplifier, FM detector, noise amplifier, and squelch gates. The 2nd LO in the IF-IC is produced from crystal OSC X1001 (14.500MHz), and the 1st IF is converted to 450kHz by the 2nd mixer and stripped of unwanted components by ceramic filter CF1001 or CF1002. After passing through a limiter amplifier, the signal is demodulated by the FM detector. Demodulated receive audio from the IF-IC is amplified by Q2019. After volume adjustment by the AF power amplifier Q2018, the audio signal is passed to the optional headphone jack or 4 Ω loudspeaker. FCC ID: K6610344140 IC ID: 511B-10344140 Circuit Description 2/3 Vertex Standard Co., Ltd. PLL synthesizer The 1st LO maintains stability from the PLL synthesizer by using a 14.500 MHz reference signal from crystal OSC X1001. PLL synthesizer IC Q1033 consists of a prescaler, reference counter, swallow counter, programmable counter, a serial data input port to set these counters based on the external data, a phase comparator, and charge pump. The PLL-IC divides the 14.500 MHz reference signal by 725 using the reference counter (20.0 kHz comparison frequency). The phase detector comparison frequency to be eight times the channel spacing (2.5kHz). The VCO output is divided by the prescaler, swallow counter and programmable counter. These two signals are compared by the phase comparator and input to the charge pump. A voltage proportional to their phase difference is delivered to the low-pass filter circuit, then fed back to the VCO as a voltage with phase error, controlling and stabilizing the oscillating frequency. This synthesizer also operates as a modulator during transmit. The RX-VCO is comprised two oscillator. The one is comprised of Q1019 and D1010, D1011, D1016, D1018 and oscillates between 406.05MHz and 426.05MHz. The another is comprised of Q1001 and D1006, D1008, D1012, D1013 and oscillated between 426.05MHz and 446.05MHz. The each VCO is programmed according to receiving frequency. And the TX-VCO is comprised of Q1020 and D1014, D1015, D1020 and oscillates between 450.000MHz and 490.000MHz according to the programmed transmit frequency. The VCO output passes through buffer amplifier Q1026, and a portion is fed to the buffer amplifier Q1029 of the PLL IC, and at the same time amplified by Q1032 to obtain stable output. The VCO DC supply is regulated by Q1006. Synthesizer output is fed to the 1st mixer by diode switch D1025 during receive, and to drive amplifier Q1031 / Q1025 for transmit. Transmitter Voice audio from the microphone is delivered via the MIC (Jack) Unit to the MAIN Unit, after passing through amplifier Q3039/Q2041, pre-emphasis, limiter (IDC instantaneous deviation control), and LPF Q2001, is adjusted for optimum deviation level and delivered to the next stage. Voice input from the microphone and CTCSS are FM-modulated to the VCO of the synthesizer, while DCS audio is modulated by the reference frequency oscillator of the synthesizer. Synthesizer output, after passing through diode switch D1025, is amplified by driver Q1031 / Q1025 and power module Q1017 to obtain full RF output. The RF energy then passes through antenna switch D1047 and a low-pass filter circuit and finally to the antenna connector. RF output power from the final amplifier is sampled by CM coupler and is rectified by D1037, D1038. The resulting DC is fed through Automatic Power Controller Q1007 to transmitter RF amplifier and thus the power output. Generation of spurious products by the transmitter is minimized by the fundamental carrier frequency being equal to the final transmitting frequency, modulated directly in the transmit VCO. Additional harmonic suppression is provided by a low-pass filter consisting of L1002 L1004, L1006 and C1017, C1022, C1028 and C1039, resulting in more than 60 dB of harmonic suppression prior to delivery to …
