Control Station Combiners (8)

These multi-channel combiners provide frequency-agile operation across their entire frequency range. Control Station Combiners may be used to reduce the number of antennas required on a communications site while also ensuring that predictable radio-to-radio isolation is maintained at all times - irrespective of individual radio’s Tx or Rx operating mode or antenna isolation characteristics.

Star Junction Combiners/Multicouplers (8)

TX RX's time-proven combiners and multicouplers provide design security for any multichannel radio system. From the most complex multi-site Homeland Security system to the simplest 2-channel private system, our products enables unsurpassed flexibility to accommodate the most challenging frequency plans, as well as future expandability. The same architecture used for transmitter combining can also be used as a preselector in complex receive systems where there is not sufficient guard-band to use combline bandpass filters.

T-Pass Transmit Combiners (11)

TX RX Systems Inc. offers a complete range of standard Transmit Combiners in the 132-960 MHz range. In order to maximize the number of channels that can be combined, high Q cavities are utilized, thus allowing frequency separations less than 100 KHz (below 800 MHz). To accommodate the large cavities required to achieve this, a unique rack, called the Peg Rack™, was designed and patented.

For applications that are more space demanding, TX RX Systems Inc. offers standard, 19" rack mount systems. Isolators are critical components of our Transmit Combiners and TX RX Systems Inc. Our isolators have a special temperature compensated design which results in greater isolation under power when compared to ...

Transmit Combiner - Expansion Channels (50)

T-Pass® transmitter multicoupler expansion channel assemblies consist of the following items:

• A 6.625” or 10” 3-quarterwave T-Pass® cavity filter;

• A dual ferrite isolator, with RF loads and coaxial cable for connection to the cavity; 

• An RF sampler to measure RF power reflected into the isolator output load; 

• Isolator and channel mounting hardware. 

Expansion assemblies for channel 2 and higher are supplied with a thruline of the correct length for the new channel frequency. Starter channels (channel 1, bottom) are supplied with a short circuit on the T-Pass loop.
