COM-TECH designs and manufactures a comprehensive range of Channel Combiners for Broadcast TV and Radio Stations.
COM-TECH Combiners are available with different cavity sizes, for low to high power applications, and with different number of poles, to match all masks and standards requirements (DVB, ATSC, ISDB, DAB).
COM-TECH develops combiners with different Combination Techniques: Manifold, Starpoint, and Balanced.
COM-TECH has exploited the Multi-Channel Combination, improving the overall Multi-Channel Performances and extending the capability to combine Adjacent Channels.
COM-TECH Combiners are easily and Fully Tunable all over their operating band, are Temperature Stabilized, and have a built in DC Short. They feature a convenient Interchangeable Connector System, and most of them are completely modular thanks to a Modular Frame System.
COM-TECH Combiners make use of innovative and proprietary design techniques, such as: XLine, DualCross, SIR, Interdigital Hairpin, EVA-Mode, MultiStep.
Low power Combiners can conveniently be integrated into 19” Rack Shelves. Medium and high power Combiners can be provided with Heat Sinks, Forced Air Cooling and Liquid Cooling to efficiently increase their input power.
The COMBINERS family is coded and categorized firstly with reference to the operating frequency band (UHF Combiners, VHF B.III Combiners…), subsequently by Combination technique (Manifold, Starpoint or Balanced), and finally by Combiner Series (CL Series, FC Series…)
