MCi designs, engineers and manufactures a breadth of high power broadcast FM multiplexers for the RF, TV and Radio broadcast industries. In fact, Micro Communications is an Emmy™ award winner for Adjacent Channel Combining Technology for the broadcast industry. Our designs use cross coupled cavities and constant impedance filters.
Micro Communications RF Broadcast equipment is optimized to handle very high power with low insertion loss and group delay performance.
High-Power FM Multiplexers
The MCi High-Power Multiplexer is used in situations where it is necessary to combine two or more FM channels to a single master antenna input. New frequencies at any power level can be added in any order by connecting another multiplexer in tandem to the previous unit.
Each unit contains a through or broadband port, in addition to an injected frequency port. The broadband port has a VSWR less than 1.08:1 over the full FM band. The cavities are easily tunable to the injected frequency.
The power handling capabilities are limited by the line size and not the cavity. Single cavity units are available for channel separation of 1.6 MHz. Dual cavities are used for frequency separations of 0.8 MHz. Injected frequency power up to 20 kW can be used.
