DUPLEXER IN BTS PDF

Duplexer unit perform duplex operation of TX and RX signals through a common antenna and filters and amplifies main and diversity received signals before they pass through the Multi coupler unit to the TRx unit. It contains a variable-gain LNA for optimal amplification of the received signal. Duplexer is used for both transmission and reception of microwave frequencies in microwave. That means one information is transmit and one information is received by the antenna. Its more useful to communication field. Duplexer is a microwave device which is mainly used in radar system when same antenna act as both transmitter and receiver.

Antenna RF Diplexer

Transceiver consists of transmitter and receiver chain radio chain. Transmitter chain converts digital data to analog data, upconvert to radio frequency, and support other functions such as filtering and amplification etc. Receiver chain takes data from antenna, amplifies it, downconvert and finally it converts analog data to digital data. A duplexer typically consists of two band pass filters connected in parallel. One filter provides a path between the transmitter and the antenna, the other provides a path between the antenna and the receiver.

Cavity Duplexer Diplexer for Bts and RF Repeater System

Conversely, it can act as a splitter to enable the signal from one feeder to be connected to two receivers or antennas. Antenna diplexers are available in a variety of formats and within a range of different powers, so that they can meet the needs of a variety of different applications needs. Antenna diplexers find many uses. Diplexers can be used in a variety of different ways, so there is no method or way in which they must be used. Accordingly they can be used for a number of different applications. It should also be noted that a diplexer is different to the traditional form of power divider or splitter. Even though the feed line is combined or split, any power that may be split is not divided between the two outputs as they are isolated from each other, and the output selection is frequency dependent.
