A reconfigurable radio communications system is disclosed. The system comprises a digital data bus, a control bus, and first and second reconfigurable radio communication units responsive to the digital data bus and the control bus. Each of the first and second reconfigurable radio communication units further include a first and a second multifunction radio transceiver, with the first reconfigurable radio communication unit responsive to at least a first antenna, and the second reconfigurable radio communication unit responsive to at least a second antenna. Each of the first and the second multifunction radio transceivers of the first and the second reconfigurable radio communication units are operable to simultaneously transmit and receive data on at least two separate channels from different frequency bands. Within the system, one of the multifunction radio transceivers is automatically reconfigurable to maintain radio communication functions previously performed by a faulted multifunction radio transceiver.

Reconfigurable aircraft radio communications system

A transceiver apparatus comprising a software-definable-radio-transceiver architecture. The transceiver apparatus comprises at least one up-conversion path including at least one configurable micro-electro-mechanical-system (MEMS) transmit filter communicatively coupled to transmit output from a digital-to-analog converter to an antenna, and at least one down-conversion path including at least one configurable-MEMS-receive filter communicatively coupled to transmit signals received from the antenna to an analog-to-digital converter. The at least one configurable-MEMS-transmit filter prevents interference on the up-conversion path from signals transmitted from the antenna. The at least one configurable-MEMS-receive filter prevents interference on the down-conversion path from signals transmitted to the antenna. A plurality of upconversion and downconversion paths can operate simultaneously and on different channel frequencies.

Software-definable radio transceiver with MEMS filters

An apparatus for transmitting and receiving multiple radio frequencies simultaneously over a single antenna is provided. The apparatus comprises a transmitter signal combining apparatus configured to communicatively couple with a plurality of transmitters, wherein the transmitter signal combining apparatus is configured to output a transmission signal based on any signals received from the plurality of transmitters. The apparatus also includes at least one transmit/receive signal duplexer coupled to the transmitter signal combining apparatus and configured to provide the transmission signal to an antenna, wherein the antenna receives an incoming radio frequency (RF) signal. Additionally, the apparatus includes a signal separation apparatus coupled to the at least one transmit/receive signal duplexer and configured to receive the incoming RF signal and provide the incoming RF signal to at least one receiver. Wherein the at least one transmit/receive signal duplexer is further configured to provide the incoming RF signal to the signal separation apparatus, and limit a direct coupling of the transmission signal into the signal separation apparatus.
