LTE Band Duplexer

AMA-4526 is a high performance duplexer, specially designed for LTE systems working in 2.5-2.7GHz band. It features flat amplitude and phase response, high isolation, low insertion loss and low group delay.

AMA-4526 is ideal for wideband high-speed digital radio applications, such as LTE and Wi-Max systems.

AMA-4526 – 2.5GHz – 2.7GHz LTE Band Duplexer

Low PIM UHF Duplexer

The AMA-4596 series are low PIM cavity duplexers, designed for UHF digital radio systems working from 400-520MHz. The typical bandwidth of the pass band is 4MHz with up to 90dB isolation to TX band.

A High performance LNA can be used to improve the system sensitivity (P/N: AMA-3312-15). Please specify RX & TX frequency band and connector requirements when ordering (eg. AMA-4596-480/490-NF).
