4.Circuit Description
4.1.Circuit Composition
4.2.TX Circuit
The TX circuit is mainly composed of three parts below:
HS8851
5

DP405 Service Manual
RF Power Amplification Circuit
RDA1846S outputs RF signal from pin 18 and enters first-level pre-drive amplifier (Q502) for initial
amplification; then it enters second-level pre-drive amplifier （Q503）and drive amplifier (Q501) for further
power amplification, ensuring sufficient drive power signal can be offered to final amplifier for ultimate
power amplification; after amplification by multiple amplifiers, the transmitted signal will complete the output
impedance match at the output terminal of final power amplifier through a section of microstripe, so as to
minimize output power loss from impedance match failure; afterwards, the transmitted signal will enter the
low pass filter through TX/RX switch.
Low Pass Filter Circuit
The low pass filter which suppresses harmonic wave is an advanced Chebyshev filter composed of lumped
parameter inductor and capacitor. On a certain basis of in-band fluctuation, the filter can improve
suppression to out-of-band harmonic wave and spurious signal.
Automatic Power Control Circuit (APC)
In the automatic power control circuit, the drain current from drive power amplifier and final power amplifier
completes switch from current to voltage through the sampling resistor and subtraction circuit which is
made of the first operational amplifier; the voltage will be compared with the APC control voltage output
from DAC at the second operational amplifier, and the error voltage that is output will change the
transmitting power through the grid bias voltage of the control power amplifier tube (including the drive level
and final level ).
4.3.RX Principle
The RX circuit is mainly composed of RF low pass filter, RX/TX switch, low noise amplifier, AT1846S,
HS8851 and audio power amplifier.
RX Circuit Front-end
The signal from antenna is sent to Q507 3SK318 and low noise amplifier (LNA) which is made of peripheral
components though RX/TX switches (D500, D501, D502 and D503) for amplification, and the amplified
signal will then be sent to U500 (AT1846S) for demodulation and output.
RX Circuit Back-end
The analogue/digital signal which is demodulated and output by AT1846S, after completing demodulation
and processing of digital signal through DSP in HS8851, will be input to digital audio processor module for
further processing, and then be switched to analogue voice signal through DAC of codec; the analogue
voice signal will finally be amplified by external audio amplifier to drive the speaker.

The radio can be set to cater to your habits or meet your needs. Settings include power, squelch level, alert
tones, sleep mode, CPS password and speech encryption, and they may vary for different dealers.
Power
Under high power, communication distance is longer but battery life is shorter; under low power,
communication distance is shorter and battery life is longer. You can set a power level for each channel.
Squelch Level
You can set the squelch level of the radio to any of 0 to 9. The higher the squelch level is, the more noise
interference there will be and the harder to receive weak signals.
Alert Tone
You can enable or disable various alert tones via the PC Tool.
14

DP405 Service Manual
Microphone Gain
Microphone gain is the value based on which an audio level is amplified. You can adjust volume by setting
a microphone gain. The higher the gain is, the higher the volume will be.
Note:
To avoid speech distortion, do not set a too high gain.
Power-saving Mode
You can enable this mode to enable the radio to automatically enter power-saving mode if it has not
transmitted or received carriers for a set period. In this mode, fewer programs are run and less battery is
consumed, so that battery life is prolonged.
CPS Password
You can set a password for the CPS (customer programming software).
Speech Encryption
You can enable/disable speech encryption for the current channel, so that speech is sent after encryption.
5.5.TOT
（
Time-out-timer
）
This function is to prevent overlong channel occupation. If the radio keeps transmitting signals for a

the side key programmed as the Quit Emergency Alarm key.
Alarm Types
Disabled:Alarm is disabled (by default). No alarm is sent when the PTT button is pressed.
Siren Only: After the radio enters the emergency state, the siren only sounds locally and the control
center will not receive any alarm signal.
Regular:The radio sends emergency alarm and audio-video alert.
Silent:The radio sends emergency alarm but no audio-video alert. When the radio receives speech
signals, the speaker will not be turned on until the PTT button is pressed.
Silent with voice:The radio sends emergency alarm without audio-video alert. When the radio receives
speech signals, there will be no audio-video alert until the PTT button is pressed.
15

DP405 Service Manual
Alarm Modes
Alarm: The radio sends an emergency alarm and then quits alarm mode.
Alarm with call: The radio sends an emergency alarm can initiates an emergency call by holding down
the PTT key.
Alarm with voice to follow: The radio sends an emergency alarm and then sends background tone
periodically.
Note:
An emergency alarm is non-speech signals sent from a radio in a group to other radios in the group,
so that alarm prompt will be given off on these radios.
To guarantee communication under emergency, an alarm call has a higher call priority than a
common call does.
5.7.Setting
The radio has been set before delivery. However, to meet customers’ requirements, it may be necessary to
set such digital functions as operating frequencies, channels, DT/DQT and automatic scan. This can be
