Nokia Flexi EDGE Dual Duplexer Module (ERxA, 1HU) Dual duplexer (DDU) module together with Dual TRX create a logical Sector
module
Min 1 DDU per sector is needed
DDU is attached to DTRX module DDU provides
duplex functionality to combine TX and RX signals to same antenna feeder multicoupling 2 antenna connections (for 1 or 2 sectors) 2 TX inputs and 4+4 RX outputs (4 RX from antenna 1 and 4 RX from antenna 2)
DDU contains
2 duplex filter 2 Low Noise Amplifiers (LNAs) with high/low gain support for RX signal 2 Bias-Ts with VSWR measurement functionality
TRX loop is controlled through the DDU
Common TRX loop for all TRXs in same sector Loop can be performed from either TX to any of 8 RX outputs (only 1 TX and 1 RX can be
simultaneously tested)

Nokia Flexi EDGE Dual TRX Module (EXxA, 2HU)
Dual TRX module (DTRX) is a 2 carrier TRX unit, used as: a stand alone TRX module (2 TRX capacity) or a Sector module with the Dual duplexer module (2 TRX capacity) or as Double Power TRX, DPTRX (1 TRX capacity) or for Intelligent Downlink Diversity, IDD (1 TRX capacity)
DTRX consists of: BB part that is common to both TRXs RF part with 2 independent transmit (TX) chains and 4 receive (RX) chains
0-2 Wideband combiner (WBC) sub-modules RX connections for diversity: 2-way diversity: 2 RX inputs/DTRX used when both TRXs are in same sector
4 RX inputs/DTRX used when TRXs of the DTRX are in 2 different sectors 4-way diversity: 4 RX inputs/DTRX used (supported only with SRC or DPTRX)
DTRX connected to system module via single Gigabit Ethernet interface Power feed from system module via single cable
