MODEL: GME9CF-*COMB-nKW
Specifications:FM multiplexer is a power synthesis device designed to achieve the synthesis of RF output signals from multiple frequency modulation transmitters into one signal output.
Standard: FM
Frequency: 87MHz~108MHz wideband
Input power:1KW~20KW
Product introduction:The FM multiplexer mainly synthesizes the RF output signals of multiple FM broadcast transmitters with different frequencies into one signal and outputs it. FM multiplexer can save the cost of configuring antennas for each transmitter and save antenna installation space.
Overview
GME9CF-6COMB-3KW type 3KW FM 6-channel combiner is a high-power FM combiner of new generation initially developed by Beijing Duoyang Gigamega Technology Co., Ltd. by applying passive radio frequency technology. It is a new product developed, standardized and serialized in its appearance and structure as well as artistic and practical. The combiner is equipped with stable and reliable performance, advanced technology, simple operation and convenient maintenance.
System Characteristics
Red copper, silvered brass and high-quality aluminum alloy have been adopted as materials of the cavity and tuning device;
Low insertion loss and reflection and high standing-wave ratio;
According to interval between frequencies, it is formed by combination of three-cavity or four-cavity filter and electrical bridge, and is of compact structure;
The overall structure is of modular design, providing upgrading space for later system expansion;
High isolation design, star-shape or bridge type or star + bridge structure is adopted as combination mode;
Anti-frequency temperature excursion design is adopted and all tuning devices are equipped with lock fasteners to prevent parameters from changing in transport and installation process;
Flat steel is adopted as support for overall outer frame for the convenience of transport and installation.
