An integrated transceiver system for an avionics radio comprises a first transceiver comprising a first duplexer coupled with a first antenna, a first transmitter that sends an RF signal to the first duplexer, a first receiver that receives an RF signal from the first antenna through the first duplexer, and a first processor in communication with the first transmitter. The first transceiver is reconfigurable for ATG communications or DME navigation. A second transceiver comprises a second duplexer coupled with a second antenna, a second transmitter that sends an RF signal to the second duplexer, a second receiver that receives an RF signal from the second antenna through the second duplexer, and a second processor in communication with the second receiver. The second transceiver is reconfigurable for ATG communications, DME navigation, transponder signal communications, or satellite communications. The first and second transceivers are integrated into a line-replaceable unit of the radio.
