Abstract
Quad band antenna interface modules include a diplexer that is configured to connect to an antenna port, a switching core that is connected to the diplexer, and filters that are connected to the switching core and are configured to provide transmit and receive ports for four frequency bands. At least one matching network port is connected between the switching core and at least one of the filters and is configured to connect a matching network thereto. Three filters and three matching network ports may be provided. A switched impedance matching network and/or a singly compensated dual diode switch also may be provided.
