DM6000-2 DM6100-2 Circuit Description
1 Frequency configuration The reference frequency of frequency synthesizer is provided by 16.8MHz crystal oscillator X3 TCXO.
The receiver adopts quadric mixing mode. The first IF is 49.95MHz, and the second IF is 450kHz. The first local oscillation signal of the receiver is produced by frequency synthesizer and the second local oscillation signal selects the 3rd harmonics of 16.8MHz of crystal oscillator X3 TCXO. The signal of transmitter is produced by frequency synthesizer directly.

Figure 2 Receiver section configuration
Front End of Receiver Signals from the antenna are filtered by BPF which consists of C570 C571 C573 C576 C574 L514 L515 D508 and D509 via RX/TX switch (D306 D307 and D309 D311). After being filtered out the useless out-of-band signals, the signals are amplified by LNA consisting of Q505 and external components. Signals from LNA are filtered again by BPF which consists of C557 C553 L510 L511 D505 D506 and

D906 before entering the 1st mixer (Q504). The PWM wave is output by MCU composed of 29 foot and then commutated to adjustable voltage after filtering to change the capacity of varactor diode D505 D506 D508 D509 and D906 to control the center frequency of BPF. 1st mixer The first IF (49.95MHz) signal is produced after mixing of the receiving signal from LNA and the 1st local oscillation signal from frequency synthesizer. The first IF signal is filtered out adjacent channel and other useless signals by crystal filter (XF501). IF Circuit The 1st IF signal from crystal filter is amplified by the first IF amplifier (Q503) before processing of IC in IF( IC501,GT3136). IF IC consists of the 2nd mixer, 2nd local oscillation, IF amplifier, limiter, frequency discriminator and noise amplifier. Frequency (16.8MHz) produced by TCXO(X3) is amplified and then selects 3rd harmonics (51.4MHZ) as the second local oscillator signal source. The second IF signals (450kHz) are generated after signals mixing of the second local oscillation (51.4MHz) and the first IF (49.95MHz) in IC501. Audio signals are demodulated and outputted by IC501 after the second IF signals are amplified and limited in IC501 and then filtered by ceramic filter(450kHz).

Receiving Audio Signal Processing: The audio processing circuit of receiver consists of IC300. Voice signals from IC300 are sent to IC301(CTCSS signaling filter circuit. Squelch Circuit
Part of the AF signal from the IC501 enters the FM IC again,and the noise component is amplified and rectified by a filter and an amplifier to produce a DC voltage corresponding to the noise level.
The DC signal from the FM IC goes to the analog port of the microprocessor(IC3).IC3 determines whether to output sounds from the speaker by checking whether the input voltage is higher or lower than the preset value.
To output sounds from the speaker,IC3 sends a high signal to the FM_MUTE and SPKSW lines and turns IC715 on through Q704 Q705and Q716. Audio Power Amplification
The audio power amplifying circuit consists of IC715 and the peripheral components. The signals are amplified by audio power amplifier to drive the speaker after collecting the receiving audio signals, voice signals and warning tone signals. The warning tone has no volume limitation.
When SPKSW is high level, Q716 is on, IC715 begins to work and the speaker sounds. Speaker Impedance: 8ohm
CTCSS Signal filtering
The audio signals after demodulation in IC13 may contain CTCSS (continuous tone control squelch system) or DCS(digital squelch)signals. The spectrum component of CTCSS/DCS is 67 to 250Hz. The filtering circuit composed of IC10 can filter out signals except CTCSS/DCS spectrum, which makes MCU decode the CTCSS/DCS more accurately.
3 Transmitter (Tx) Transmitter Power Amplifier
Figure 4 Schematic Diagram for Power Amplifier and Antenna Switch
The modulated RF signals from VCO are amplified by Q10, Q303 before the power amplification in IC302.
Gate bias of Q303 and IC302 is controlled by APC circuit, so the output power of transmitter can be
4
controlled conveniently by changing the gate bias voltage. APC(Automatic Power Control)
D313 and D314 are power amplification current detector, IC303 is power amplification current sampling amplifier and power comparison amplifier.
The power amplification current and IC303A output will increase with oversized output power of transmitter. When the output voltage of IC303B decreases, the bias voltage of Q303 and IC302 will decrease, finally the output power of transmitter will decrease or vice versa. Thus, the output power of transmitter will keep stable under any different working condition.
MCU can set the power by changing the voltage input to IC303B. Audio Signal Processing of Transmitter
Figure 6 Schematic Diagram for Audit Circuit of Receiver
The audio signal processing circuit of Transmitter consists of IC14 and IC1. Voice signals from MIC
are sent to VCO for modulation together with CTCSS/DCS after amplification, limitation and filtering. IC1 is a bais band processor. AGC circuit consists of D12, D13 and Q20,Q21. The signal amplitude is reduced to ensure no
distortion in case of oversized MIC signal. Q12, the power switch of voice processing circuit, controlled by MCU, will give power supply to IC14
only during transmission.
4 PLL Frequency Synthesizer

Figure 7 Schematic Diagram for Frequency Synthesizer
The DM6000-2 adopts PLL frequency synthesizer. Frequency synthesizer consists of reference oscillator, voltage controlled oscillator (VCO),
programmable frequency divider (PFD), phase comparator and low pass filter (LPF).
RX VCO Unit consists of Q4 D3 D5 L12 C45 C49 and C51.
TX VCO Unit consists of Q6 D4 D6 D7 L11 C46 C50 and C52, D7 is the modulation circuit of VCO.
IC8 (SKY72310) is PLL integrated circuit and contains programmable parametric frequency divider (PPFD), programmable frequency divider (PFD), phase comparator and charge pump, etc.
Low pass filter consists of R7 R159 R160 C171an C196. Reference frequency is provided by X3 (TCXO, 16.8MHz). Reference frequency of TCXO (Temperature-controlled Crystal Oscillator) is divided by PPFD in IC3 to
produce reference frequency of 5kHz or 6.25kHz (controlled by MCU based on the set channel frequency).
The oscillation frequency of VCO is compared with reference frequency to produce error signal after divided by PFD in IC607. The error signal is filtered by low pass filter before changing the VCO frequency to the set value in VCO (it is locking).
N=FVCO/FR
N:Division Frequency FVCO:VCO Oscillation Frequency
FR:Reference Frequency
Lock lost detection: When PLL is out of lock, IC pin4 will output low level signal to MCU,and then MCU prohibit transmitter from transmitting with a warning tone. Q8, the power filter, can provide PLL with more purified power to reduce the noise of frequency synthesizer.

2 of the DMR protocol. it completes the entire physical layer and data link layer, and voice processing part of the call control layer of DMR compliant with ETSI TS 102 361.

6 Voice Circuit: The station is equipped with Voice Prompt Function, which is very useful during night or under dark
condition. The speaker will voice the current channel number when changing the channel every time because of
the voice memory chip (IC15), which stores channel voice prompts. It will repeat the current channel number once pressing “Voice Prompts”.
The speaker will voice the current channel number under standby state if the Voice Prompt Function is set. Press “Voice Prompts” for reset to switch voice types. Press “Voice Prompts” repeatedly for power connection, then the voice types will be switched in circle in the order of “Chinese male voice—English male voice—Chinese female voice—English female voice—no prompts”.
