Abstract
A portable radio provides operation in LTE and LMR radio bands. Improved filtering in the LTE receive path is provided through the use of a linear duplexer and a SAW filter. The SAW filter is implemented as a duplexer with one port terminated to provide a filter for the LTE RX path. The linear duplexer and SAW filter provide filtering for an LMR TX signal and an LTE TX signal which are simultaneously present at an LTE antenna of the radio. The linearity of the linear duplexer which reduces LTE TX and LMR TX signal levels combined with the selectivity of the SAW filter prevents intercept intermodulation in the LTE RX path.
