Product Description

618F series digital FM broadcast transmitter is based on a new digital FM exciter, supplemented by audio transmission equipment, power amplifier and power synthesis filter. Through all-digital audio processing, the software directly implements digital filtering of audio, pre-emphasis, instantaneous, pilot generation, stereo encoding and other processes. MPX signals are then modulated and output by direct digital synthesis technology to transmit high-quality FM broadcast signals.


 MOSFET all-solid-state technology

 Unique distribution and synthesis technology

 Modular design concept

 Power amplifier module and switching power supply adopt building block structure

 Parallel redundant design to reduce the interruption rate

 Backup redundant design of the exciter: the main and backup exciters are backed up and switched automatically (backup exciter and switch are optional)

 Microprocessor control technology with self-diagnostic function

 Perfect technical data detection and monitoring system and computer control software with perfect functions

 With TCP / IP, SMS cat, RS232 communication interface, computer management and monitoring can be used

 The switching power supply is provided with over-voltage, over-current, under-voltage, over-temperature, short-circuit, lightning protection, etc.

 The whole transmitter is equipped with VSWR, over-excitation, phase loss and lightning protection etc.
