Anatech Electronics introduces a high performance 380-385/390-395 MHz Cavity Duplexer used in T-GSM-380, Aerospace, and UHF applications. The uplink and downlink bands provide a low passband loss of < 1.2dB, and a high isolation of > 80dB. This Duplexer is capable of handling upto 100W of average power, and can withstand extreme weather conditions. A weatherproof version is also available.

The MtronPTI LF9422 L/S Band LC Filter Diplexer is custom designed for small form factor UAV-ISR platforms. Unlike open frame designs, the 1” x 1” wash-proof surface mount package is sealed, allowing automated assembly with no drift after board cleaning.

Narda West’s AMPS B Band Duplexer provides highly selective receive/transmit combining
The GPS Diplexer shown here is one of the many variations of GPS diplexers ComNav has available. The ceramic construction filter provides a temperature stable, low loss device which can with stand harsh environments at a low cost. Numerous other types are available with smaller size and /or higher isolation for different GPS applications...
K&L Microwave’s tunable filters and bandpass/bandstop diplexers are usually used in test and measurement applications. Diplexers feature broadband matching at the common port, low insertion loss, and high isolation. Tunable filters are useful because they provide high performance in a single package. They can also be offered to cover frequencies as low as 800 KHz or as high as 3 GHz.

MtronPTI offers the UFDX9999-002 C-band cavity diplexer/splitter assembly designed to support rugged, high-performance communication links that require full duplex operation in airborne, land, maritime, and deep space applications.

K&L Microwave’s e-band diplexer consists of two waveguide bandpass filters specially designed to pass a relatively wide range of the spectrum: from 71 to 76 and 81 to 86 GHz respectively
This diplexer model has been designed for applications that require a high level of TX-RX isolation. It has a temperature range of -20 to +85°C and a maximum VSWR of 1.5:1.
