Product Description

The Telewave TTPD-8642 Bandpass-Band Reject Duplexer 806-960 MHz, is designed for the 806-960 MHz frequency band. Bandpass / Band-Reject cavities utilize an exclusive Telewave coupling technique to provide a true bandpass response, while rejecting a specified frequency band. Maximum transmitter-to-receiver protection is achieved across the full transmitter and receiver bands, with very low insertion loss.

The TTPD-8642 is a compact, rack mounted duplexer on a 5.25” x 19” panel, with a power rating of 350 watts. Heavy-duty materials which include ¼-inch top and bottom plates add to the rugged design of these duplexers. All connectors and tuners are silver-plated, and beryllium copper finger stock contactors assure long life, high “Q” performance, and mechanical stability. Solid copper semi-rigid cable and non-ferromagnetic materials virtually eliminate internal intermod-generation

A threaded Invar tuning rod and temperature compensator provide frequency stability across the full temperature range. All cavity inputs are heavily grounded for greatest static and lightning protection. All duplexers are tuned and tested with customer-specified frequencies prior to shipping. No further adjustments should be required. The positive locking mechanism makes field-tuning simple if frequency changes are necessary.
