1 Product Overview
This section includes a product overview of CDU-D, a combining and
distribution unit used in high-capacity cells where high coverage is required.
1.1 Main Functions
This section describes the main functions of CDU-D:
• Combining of six TX signals to one antenna
• Distribution of two RX signals from two independent RX antennas
• Simultaneous transmission and reception on one antenna
• Automatically tuned cavity combiners operated by step motors
• Possibility of configurations with 12 TRUs connected to two antennas
• Baseband hopping support
• Power and supervision of an external Tower Mounted Amplifier (TMA) via
the RX antenna cables (GSM 1800)
1.2 Variants
CDU-D is available for:
• GSM 900
• GSM 1800
CDU-D for GSM 900 is equipped with a duplexer (FUd). CDU-D for GSM 1800
can be equipped with or without a duplexer (FUd or FU). The latter version
requires separate antenna feeders for the TX and RX signals, and TMA.
