2.3.2.1.1 Remote Duplexer and Low Noise Amplifier
The Remote has an internal Duplexer that is optimized to provide the desired RF
band-pass filtering and in-band equipment isolation between FWD and REV paths.
The Duplexer contains up to two REV path Low Noise Amplifiers (LNA for PRI and/or
SEC reverse paths). Each LNA (shown in Figure 2-8) is a high quality low noise
amplifier providing the Prism reverse path with nominal 30dB REV gain and system
NF of 5dB per RX path. The Duplexer and its LNA are housed in the RF Module, and
are not field servicable.
