Duplex Filter
The duplex filter is a filter/combiner that allows a single antenna to be used for both the LTE transmit
signal as well as the LTE receive signal. The duplexer removes transmitter noise in the receiver sub-
band. It also prevents the transmitter signal from entering the multicoupler and receiver at excessive
levels.
Two duplex filters are utilized to feed both paths of a single cross polarized antenna or two antenna
spaced far enough apart to provide the receiver with two uncorrelated signals.
