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.

The Avago ACMD-7407 are highly miniaturized duplexers designed for use in UMTS Band 2 handsets and mobile data terminals.
Narda West’s AMPS Band High Isolation Duplexer provides highly selective receive/transmit combining
Multilayer Diplexer (DPX202170DT-4021A1) by Digi-Key.
K&L Microwave’s tunable filters and bandpass/bandstop diplexers are typically used in test and measurement applications. The diplexers feature broadband matching at the common port, low insertion loss, and high isolation. What makes tunable filters useful is that they provide high performance in a single package. Tunable filters can be offered to cover frequencies as low as 800 KHz or as high as 3 GHz.
The Avago ACMD-7606 is a highly miniaturized duplexer designed for use in UMTS Band 8 (880 – 915 MHz UL, 925 – 960 MHz DL) handsets and mobile data terminals.
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.
