RDA Chip Circuit
This chip is highly integrated. Its function includes voice signal processing/modulation/demodulation,
DSP, VCO, PLL, LNA and RF IF. The voice signal from MIC goes to RDA chip for amplification. Next,
the amplified voice signal will undergo a series of processing including A/D conversion, filtering,
pre-emphasizing, gain control, amplitude limit and D/A conversion. Then the analog voice signal is
delivered to VCO and amplified to a signal with 8dBm. When the RX RF signal enters this chip, it
would experience demodulation, filtering, de-emphasizing and gain control. Finally, the signal is
output to the audio amplifier.
TX Circuit
Page 13
Circuit Description Service Manual
10
The modulated RF signal from RDA chip goes to Q407 and Q402 for amplification, and then further
amplified by Q403. Then the amplified signal is delivered to low-pass filter to filter out the high-order
harmonics. Finally, it is sent via the antenna.
RX Circuit
After going through LPF and amplitude limiter, the RF signal received from the antenna enters Q501
LNA for amplification. Then the BPF will filter the signal to remove other unwanted signals. The
resulting signal is delivered to RDA chip for demodulation. After that, the voice signal from
demodulation is output U302 for amplification, which is finally output from the speaker.
Power Circuit
LDO U619 converts the 6V power supply into two 5V, which LDO U621 will convert into two 3.3v
power supplies, powering VCC and VDD respectively. VCC powers CPU, while VDD powers RDA
chip. Then Q409 converts the 5V power supply to VT to power the TX circuit.

After entering RDA chip via MIC, the voice signal will undergo A/D conversion to get digital signal, which
will be delivered to DSP for further processing such as filtering, amplification, amplitude-limiting and
pre-emphasizing. Then the resulting voice signal is modulated to the internal VCO and output after being
amplified by the driver amplifier. At the RX end, the received RF signal will go to LNA for amplification
first, and then go to IF demodulation circuit to get demodulated voice signal. After gain control, such
signal is converted into digital signal, which will enter DSP for further processing such as filtering,
amplification and de-emphasizing.
The function of RDA is subject to MCU U622 and its reference clock signal is from 26MHZ crystal
oscillator. This chip is applicable to UHF (400~520MHZ) and VHF (134~174MHZ). The NF can be up to
3dB and IIP3 up to -6dBm, meeting GB and FCC requirements. Its RF output may reach up to 8dBm.

The modulated RF signal from RDA chip goes to Q407 and Q402 for amplification, and then further
amplified by Q403. Then the amplified signal is delivered to low-pass filter to filter out the high-order
harmonics. Finally, it is sent via the antenna. The control signal “VT” is used to control the operation of
driver amplifier (Q407 and Q402). U401 works for auto power control (APC).

The RF signal is received via the antenna. After going through LPF and amplitude limiter, the signal is
amplified by Q501 LNA. The LNA adopts 2SC3356 with current <5mA and its gain is about 12dB.
Next, the BPF will remove the interference signal in amplified RF signal. Then the resulting signal goes
to RDA chip for further processing. The processed signal is delivered to U302 for amplification and finally
output by the speaker.

7.2 Preparations
Place the board to be tested on the test fixture (please ensure good connection between each test point
and the fixture), and connect the board to a power supply with DC voltage of 6.0V.
7.3 Wired Clone
7.3.1
Instructions:
Connect two radios using a cloning cable. Simultaneously hold MONI key to power on the source
radio so that the wired clone mode will be entered after 2 seconds, and then press MONI key to
switch to factory wired clone mode (when the wired clone mode is entered, the user wired clone
mode is defaulted); then directly power on the target radio to enter the user mode.
The LED flashes red once after the source radio enters Wired Clone mode. Press PTT to clone data
to the target radio.
During communication, the LED of the source radio glows red, and the LED of the target radio glows
green. When the communication ends, green LED of the source radio glows and the green LED of
the target radio goes out, which indicates the preparation for another clone.
If any abnormal situation occurs during communication, the source radio will flash orange LED and
will stop communication for another cloning.
When cloning ends, the source radio goes back to the standby status. Press PTT again to begin
another cloning operation.
7.3.2 LED Indication during Cloning
Orange LED flashes: an error occurs during cloning. In this case, press any key other than the power
switch to turn it off.
Green LED glows: the cloning is done successfully.

7.3.3 Difference between Factory Clone Mode and Clone Mode
Clone Mode: Only clone relevant data in user mode (such as frequencies). Tuning parameters like
tuning frequency, tuning item and base band parameter will not be cloned.
Factory Clone Mode: Clone all the data excluding serial No.

7.6 Method and Procedure:
7.6.1
Description of Tuning Procedures
Simultaneously hold PTT, MONI and Power On/Off Key for more than 2s to enter tuning mode (LED
flashes orange). After the keys are released, the radio will enter the tuning item in this mode (the item
entered depends on the position where the Channel Selector knob locates). And the LED will glow red
or green according to the specific tuning item.
Or connect a programming cable to the radio for real-time tuning in PC Programming Mode.
7.6.2 Description of Tuning Items
You can use MONI key to select your desired values.
7.6.3 Specific Operations and Requirements
Note:
By default, channel 1, 2, 3, 4 and 5 use wide band, while channel 6, 7, 8, 9 and 10 use narrow
band. Remember to connect the antenna properly.
Press PTT+MONI key to turn on the radio.
