Pasternack RF mixers (also known as double balanced mixers or frequency mixers) are passive microwave circuits that can create new frequencies when two signals are applied to it. With passive RF mixers, the output frequency is always lower than the sum of the two input frequencies. The two input frequencies, known as RF and LO, modulate inside the radio frequency mixer to create the IF output frequency.
Pasternack’s 50 Ohm RF mixers are available with SMA connectors and have operating RF and LO input frequencies ranging from 2 GHz to 18 GHz and output IF frequencies between DC and 8 GHz. RF mixers from Pasternack have a maximum LO power of 10 dB and a maximum LO conversion loss of 7.3 dB.
