Sell GSM Duplexer

Description

Duplexer is a device separating two-way signals of different frequencies, and is a combination of uplink filter connecting with downlink filter in a yet-to-be-determined pattern. From that power divider separates same-frequency signal into two parts of equal power, duplexer picks up the signals of different frequencies from the public port(ANT port), and allocates the signals separately to the transmission port (TX) and receive port(RX).

This products adopts the internationally advanced High-Q CAVITY structure, together with cross coupling and transmission zero technology, which ensure low insertion loss, high power capacity, high suppression, stable temperature performance , etc.We provided OEM products for many renowned wireless base station and repeater equipment suppliers. The duplexer is used to prevent large signals entering into the front terminal of the receiver to cause saturation or even burn-out of receiver, and prevent the influence of transmitter noise on the sensitivity of receiver.
