Description

Preselector-

TX RX has designed application-specific multi-cavity filter products for use in limiting the bandwidth in front of a multiple-receiver system (Preselector) or after a multiple-transmitter system (Post Selector). Size and complexity range from a model built from three helically-loaded 1.3-inch rectangular resonators for relatively low-selectivity receive-only applications, where 2 dB of loss can be tolerated, to four 6.625-inch cavities that can handle 400 watts with high selectivity and loss of 1 dB or less.

 

Manufacturer

TxRx, Combilent

TX RX Systems, Inc. was founded in 1976 and is located in Angola, NY, a suburb of Buffalo. The company quickly became the industry leader in providing RF Conditioning products in the Land Mobile Radio market, aided by breakthrough inventions in T-Pass® Transmit Combiner, Auto-Backup® Tower Top Amplifier, base station antennas,  etc.  Over the years, TX RX’s RF Infrastructure Products have played a critical part in improving and optimizing numerous mission critical radio networks for both Public Safety and general two-way radio users. TX RX Systems was acquired by Bird Technologies Group in 1995 and became the “go-to supplier” for LMR applications in VHF, UHF, and 700/800 MHz frequency bands. In 2018, Indutrade, a European conglomerate based in Sweden, acquired TX RX from Bird.  TX RX joined Combilent, a Denmark company also owned by Indutrade, to form the Combilent Group.    The new TX RX will continue the tradition of offering best-in-class solutions for our customers, while leveraging the combined strength and resources of both companies in R&D, operations, and sales support.
