MTS LiTE / MTS 2 Duplexer

The Duplexer is a Preselector with Integrated Receiver Multicoupler (RMC) and a Post Filter with a digital power
monitor (DPM) combined into one unit. These form the two bandpass filters that make up the Duplexer; one is a
receive filter and the other a transmit filter.
Note: The MTS LiTE Duplexer is common with the MTS 2 Duplexer.
Caution: Do not remove the screws entirely because the filter will drop.
