4.1 TX Part
The TX part handles the transmission of signals from the TRUs to the antenna.
The TX part for each antenna consists of:
• A circulator
• A TX Band-Pass Filter (TXBP) (GSM 1800 and GSM 1900 versions only)
• A duplex filter (duplexer) (GSM 900 version only)
• A Measurement Coupler Unit (MCU)
Circulator
The circulator provides a uni-directional transmission
path and protects the transmitter inputs from reflected
signals.
