Patent

CA 2627978

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.
