SWITCHABLE RF TRANSMIT/RECEIVE MULTIPLEXER

摘要

A switchable RF transmit/receive (TX/RX) multiplexer, which includes a group of RF TX bandpass filters, a group of RF TX switching elements, and a group of RF RX bandpass filters; is disclosed. The group of RF TX bandpass filters includes a first RF TX bandpass filter and a second RF TX bandpass filter, such that each of the first RF TX bandpass filter and the second RF TX bandpass filter is coupled to a first filter connection node. The group of RF TX switching elements includes a first RF TX switching element coupled between the first filter connection node and a first common connection node, which is coupled to a first RF antenna. Each of the group of RF RX bandpass filters is coupled to the first common connection node.
