ABSTRACT:
A floating FET mixer (1) comprises: a field effect transistor, FET, (2) having a gate (11), a drain terminal (4) and a source terminal (5), an LO port (10) at which an LO signal from a local oscillator is coupled to the gate (11), primary windings (9) of a balun (3) across the drain terminal (4) and the source terminal (5), secondary windings (8) of the balun (3) coupled at its opposite ends to ground and an RF port (7), respectively, a center tap (12) on the primary windings (9), and a series biasing element (20) on the gate (11) biasing the FET (2) near pinch off.
