A mixer including a first mixer port (12), a second mixer port (14), a third mixer port (16). A first hybrid device (20) is responsive to the first mixer port and has first and second ports. A second hybrid device (40) is responsive to the second mixer port (14). The third mixer port (16) is responsive to the second hybrid device and a switching device. The switching device (30) includes a first port (31) responsive to the first port of the first hybrid (20), a second port responsive to the second port of the first hybrid (20), third (34) and fourth ports (36) coupled to the second hybrid (40), and a switching element. The switching element includes a first field effect transistor (60) responsive to the first port (31) and coupled to the third port (34) and a second field effect transistor responsive to the second port (32) and coupled to the fourth port (36).
