To provide differential radio communication equipment in which a leak is reduced by the differential characteristics of a power amplifier (PA) and coupling is reduced by the differential characteristics of a differential low noise amplifier (LNA).

A differential antenna 12 is connected to a duplexer 14. The receiving portion of the duplexer 14 is the input of a differential LNA 16. A first filter 18 is interposed between the differential output of the LNA 16 and a first mixer 20. A signal processing part 22 receives a differential output signal from the first mixer 20. A second mixer 24 receives the differential output signal from the signal processing part 22. A second filter 26 receives the differential output signal from the second mixer 24. A PA 28 is interposed between the transmitting portions of the second filter 26 and the duplexer 14.
