FCC ID: K66VX-2500V Circuit Description Vertex Standard Co., Ltd. 1/3 VX-2500V Circuit Description 1. Overview The VX-2500V is a VHF/FM mobile transceiver designed to operate in the frequency range of 148 to 174MHz(C Band). 2. Circuit Configuration by Frequency The receiver is a double-conversion superheterodyne with a first intermediate frequency (IF) of 44.25MHz and a second IF of 450kHz. Incoming signals from the antenna are mixed with the local signal from PLL to produce the first IF of 44.25MHz. This is then mixed with the 43.8MHz second local oscillator (using the 14.6MHz TCXO) output to produce the 450kHz second IF. This is detected to give the demodulated signal. The transmit signal frequency is generated by PLL VCO, and modulated by the signal from the microphone. It is then amplified and sent to the antenna. 3. Receive Signal Path Incoming RF signals from the antenna connector are delivered to the RF Unit, and pass through a low-pass filter (LPF) antenna switching network consisting of coils L1002, L1003, and L1007, capacitors C1004, C1009, C1016, C1019, and C1282, and antenna switching diodes D1005, and D1007 for delivery to the receiver front end. Signals within the frequency range of the transceiver are then passed through a varactor-tuned bandpass filter consisting of L1008, L1009 before RF amplification by Q1011 (2SC4226). The amplified RF is then band-pass filtered again by varactor-tuned resonators L1019, L1023 to ensure pure in-band input to 1st mixer Q1026 (3SK228). Buffered output from the VCO Unit is amplified by Q1021 (2SC5107) and low- pass filtered by L1030, L1032 and C1184, C1188, C1192 to provide a pure 1st local signal between 192.25 and 218.25MHz(C Band), 178.25 and 204.25MHz. The 44.25MHz 1st mixer product then passes through monolithic crystal filters XF1001, and is amplified by Q1029 (2SC4215Y) and delivered to the input of the FM IF subsystem IC Q1028 (TA31136FN). 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 TCXO X1001 (14.600MHz), 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 CD1001 (CDBC450CX24). Detected audio from Q1029 is applied to Q2016(AK2345) and audio low-pass filter. After volume adjustment by Q2014(M62364FP), the audio signal is amplified by the AF power amplifier Q1509 (TDA2003H) and passed to speaker jack. 4. Transmit Signal Path Voice audio from the microphone is delivered via the Mic (Jack) Unit to the FCC ID: K66VX-2500V Circuit Description Vertex Standard Co., Ltd. 2/3 PANEL Unit, after passing through amplifier Q2022 (NJM2902V), Mic gain- volume Q2014 (M62364FP) pre-emphasis Q2015 (NJM2902V),and limiter Q2016 (IDC instantaneous deviation control), 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 D1022 (1SS321), is amplified by driver Q1022 (2SC5415E) / Q1025 (2SC5107) and power module Q1014 (RA30H1317M) to obtain full RF output. The RF energy then passes through antenna switch D1005 / D1007 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 D1011,D1012(HSM88AS2). The resulting DC is fed through Automatic Power Controller Q1003 (NJM2902V) 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, L1003, L1015, L1016, C1004, C1282, C1009, C1016, C1019, C1025, C1034 and C1283, resulting in more than 60dB of harmonic suppression prior to delivery to the RF energy to the antenna. 5 PLL Frequency Synthesizer PLL frequency synthesizer consists of the VCO Q1013 (2SK508-K52:RX) and Q1015 (2SC4226-R24:TX), VCO buffers Q1018 (2SC5107-0), Q1020 (2SC5107-0), Q1021 (2SC5107-0), PLL subsystem IC Q1023 (SA7025DK) and 14.6MHz reference crystal X1001. The frequency stability is +/- 2.5ppm within temperature range of –30 to +60 degree. The output of the 14.6MHz reference is applied to pin 8 of the PLL IC. While receiving, VCO Q1013 oscillates between 192.25 and 218.25MHz(C Band), 178.25 and 204.25MHz according to the transceiver version and the programmed receiving frequency. The VCO generates 192.25 and 218.25MHz(C Band), for providing to the first local signal. In TX, the VCO generates 148 to 174MHz(C Band). The output of the VCO is amplified by the Q1020 and routed to the pin 5 of the PLL IC. Also the output of the VCO is amplified by the Q1021 and routed first local /Power Module according to D1022. The PLL IC consists of a prescaler, fractional divider, reference divider and phase comparator and charge pump. This PLL IC is fractional-N type synthesizer and performs in the 40 or 50kHz reference signal, which is eighth of the channel step (5, or 6.25kHz). The input signal from pin 5 and 8 of the PLL IC is divided down to the 20kHz and compared at phase comparator. The pulsed output signal of the phase comparator is applied to the charge pump and transformed into DC signal in the loop filter. The DC signal is applied to the VCO and locked to keep the VCO frequency constant. PLL data is output from DCS_E (pin100), CLOCK (pin2) and PLL_E (pin98) of the microprocessor Q2013. The data are input to PLL IC when the channel is changed or when transmission is changed to reception and vice versa. A PLL lock condition is always monitored by the pin20 of the Q2013.…

FCC ID: K66VX-2500V Alignment Vertex Standard Co., Ltd. 1/6 VX-2500V Alignment Introduction The VX-2500V is carefully aligned at the factory for the specified performance across the frequency range specified for each version. Realignment should therefore not be necessary except in the event of a component failure, or altering version type. All component replacement and service should be performed only by an authorized Vertex Standard representative,or the warranty policy may be void. The following procedures cover the sometimes critical and tedious adjustments that are not normally required once the transceiver has left the factory. However, if damage occurs and some parts subsequently are placed, realignment may be required. If a sudden problem occurs during normal operation, it is likely due to component failure; realignment should not be done until after the faulty component has been replaced. We recommend that servicing be performed only by authorized Vertex Standard service technicians who are experienced with the circuitry and fully equipped for repair and alignment. Therefore, if a fault is suspected, contact the dealer from whom the transceiver was purchased for instructions regarding repair. Authorized Vertex Standard service technicians realign all circuits and make complete performance checks to ensure compliance with factory specifications after replacing any faulty components. Those who do undertake any of the following alignments are cautioned to proceed at their own risk. Problems caused by unauthorized attempts at realignment are not covered by the warranty policy. Also, Vertex Standard reserves the right to change circuits and alignment procedures in the interest of improved performance, without notifying owners. Under no circumstances should any alignment be attempted unless the normal function and operation of the transceiver are clearly understood, the cause of the malfunction has been clearly pinpointed and any faulty components replaced, and realignment determined to be absolutely necessary. The following test equipment (and thorough familiarity with its correct use) is necessary for complete realignment. Correction of problems caused by misalignment resulting from use of improper test equipment is not covered under the warranty policy. While most steps do not require all of the equipment listed, the interactions of some adjustments may require that more complex adjustments be performed afterwards. Do not attempt to perform only a single step unless it is clearly isolated electrically from all other steps. Have all test equipment ready before beginning, and follow all of the steps in a section in the order presented.

Correct alignment is not possible with an antenna. After completing one step, read the following step to determine whether the same test equipment will be required. If not, remove the test equipment (except dummy load and wattmeter, in connected) before proceeding. Correct alignment requires that the ambient temperature be the same as that of the transceiver and test equipment, and that this temperature be held constant between 20 and 30 ° C (68 ∼ 86 ° F). When the transceiver is brought into the shop from hot or cold air, it should be allowed time to come to room temperature before alignment. Whenever possible, alignments should be made with oscillator shields and circuit boards firmly affixed in place. Also, the test equipment must be thoroughly warmed up before beginning. Note: Signal levels in dB referred to in the alignment procedure are based on 0dB μ EMF = 0.5 μ V. Setup the test equipment as shown for transceiver alignment,apply 13.8V DC power to the transceiver.
