Overview
The transmitter is divided into two parts: the exciter and amplifier unit. Block diagram
is shown below. Amplifier unit is also the data processing and control unit, it can
complete external communications and feedback to control exciter, and display data of
transmitter.
System Characteristics
LDMOS solid-state technology.
Perfect protection measures to ensure the safe operation of equipment, with a VSWR,
temperature, over-drive protection.
Modular design for flexible selection of multiple exciters.
“Integrated” design, small size, easy installation, the machine is a minimum standard 19
“8U cabinet, you can also choose 2 meters 19” rack cabinet to install two transmitters in
standby multi-transmitters.
Intelligent monitoring system, LCD display operating parameters.
RS485 interface, you can achieve remote control. Remote control software can be
customized by the user or develop their own software.
Simple, just turn on the power switch of amplifier unit, boot action finished.
