Any area with a potentially explosive atmosphere, e.g. orlop deck of the ship, storage
and transportation equipment for fuel and chemical, where the air with chemical
substance, particle or iron dust.
Any place near blasting sites or area with electrical blasting cap.
It is also prohibited to change or charge the battery in any area with a potentially
explosive atmosphere.
* Antenna
If the antenna has been damaged, do not use the radio. Damaged antenna may cause
light burning to skin.

The reference frequency of RD1846S is generated by 12.8MHz crystal oscillator X500
TCXO.
3.3 Principle of Receiver (RX)
Figure 3.3 Principle of Receiver
Receiver is mainly used in receiving, selecting, amplifying, transforming, demodulating
etc. and other processing like audio signal amplifying, filtering. Audio part mainly is used
to post emphasis, amplify and filter audio signal.
Receiver Front End
Low noise amplifier is located in the receiver front-end, mainly used in amplifying small
radio frequency signal, in order to provide certain intensity and SNR of RF signal for
subsequent signal processing.
Signals from the antenna transmission (RX/TX) switch (D502 D501, D503, D504), are
sent to Q507 3SK318 and peripheral components consisting of low noise amplifier (LNA)
for enlarging. The enlarged signal will be sent into IC4 (RDA1846S) to demodulate into
output audio signal. 3sk318 noise coefficient is 1.4 db, G about 18 db.
There is input and output match for LNA. Input match adopts best noise figure while
output use maximum power to match, i.e., the amplifier output impedance adjusted to the
load impedance (typically 50 ohm); Input and output impedance of the low noise pipe is
usually high impedance, so the matching circuit using inverted L

Audio signal from IC4 (RDA1846S) processed through LT1801, then through the
volume potentiometer, to the audio power amplifier U600 (TDA2822).
Audio power amplifier
U600 and peripheral components makes up the audio power amplifier circuit
Q601 base is the control end. High level: U2 begins to make audio; Low level: closed.
Receive audio signals, voice signals, alarm sound signals are summarized and sent to
speaker through audio power amplifier. Among them, the alarm sound will not be limited
by volume control. The speaker impedance: 16 ohms.
3.4 Principle of Transmitter (TX)
Power amplifier and antenna switch principle diagram
Modulated signal from IC4 (RDA1846S), enlarged via Q502, Q503, Q501, are sent to
Q500 power amplifier, and then transmitted through receiving toggle sending into the low
pass filter. LPF will improve as much as possible to harmonic stray signal attenuation in
certain condition of fluctuations in performance. Q500 output power: 4W
Q502 2sc5108 pre-amplifier, mainly to preliminary enlarge output RF signal of
RDA1846S, to provide a certain intensity of the amplifier after excitation signal.
Q503 2sc3356 pre-push RF amplifier is mainly used to provide a certain level of
intensity of excitation signal for subsequent amplifier, so as to guarantee the driving
amplifier can output enough power, to push the last stage power amplifier.
Q501 RD01 promote RF amplifier, is mainly used to promote the last stage power
amplifier, to ensure the output power of the last stage power amplifier to achieve the rated

output power of the transmitter. The output is about 0.5 W, G about 14 db.
Q500 RD07, end RF power amplifier, is part of the important and critical level. The
output power and efficiency level at the end power amplifier are almost equal to
transmitter output power and efficiency. The stability of the last stage amplifier basically
represents the stability of the transmitter also. Output is 0.8W, G about 12db.
Q500 Q501 grid bias is controlled by APC circuit. Change the gate bias voltage, can
easily control the size of the transmitter output power.
APC (automatic power control) circuit
This circuit changes the gate bias voltage by testing the change of the input to the
power amplifier drain current and changes the output power by changing the gain.
R520 R521, R522 are power amplifier current detection, U502A is the current sampling
amplifier power amplifier. U502B is the comparison power amplifier.
If the transmitter output power is too large, the power amplifier current increase,
U502A output rise, U502B output voltage drops, applied to Q500, Q501 bias voltage to
drop, lower the transmitter output power, vice versa. In this way, the transmitter output
power is stable under different working conditions.
MCU achieves the goal of setting power by changing the input to the voltage on the
U502B.
Transmitter speech signal processing
MIC signal is sent through the inside and outside MIC switch circuit into No. 11 feet of
IC4 (RDA1846S) to modulate the carrier.
