DUAL DUPLEXER MODULE (ERxA)

Dual duplexer (DDU) module together with Dual TRX create a logical Sector moduleMin 1 DDU per sector is neededDDU is attached to DTRX module

DDU providesduplex functionality to combine TX and RX signals to same antenna feedermulticoupling2 antenna connections (for 1 or 2 sectors)

2 TX inputs and 4+4 RX outputs (4 RX from antenna 1 and 4 RX fromantenna 2)

DDU contains2 duplex filter2 Low Noise Amplifiers (LNAs) with high/low gain support for RX signal2 Bias-Ts with VSWR measurement functionality

TRX loop is controlled through the DDUCommon TRX loop for all TRXs in same sectorLoop can be performed from either TX to any of 8 RX outputs (only 1 TX and 1

RX can be simultaneously tested
