Abstract
A mixer (1) comprising, an RF port 2 and an LO port (3) supplying two diodes (7), a junction (8) of the diodes (7) referenced to ground (9), and a differential amplifier (19) being supplied with +IF and -IF from outputs of the diodes (7), and the differential amplifier (19) supplying low LO AM noise and low frequency response of an IF port (18) at an output (20) of the differential amplifier.

A mixer comprising:
- an RF port and an LO port supplying two diodes, a junction of the diodes referenced to ground, and a differential amplifier being supplied with +IF and -IF from outputs of the diodes, and the differential amplifier supplying low LO AM noise and low frequency response of an IF port at an output of the differential amplifier.
A mixer comprising:
- an RF port and an LO port supplying two diodes of the same polarity, a junction of the diodes referenced to ground, and +IF and -IF extracted by diplexers at junctions of the RF and LO ports with the diodes.
