RF Mixers from Pasternack and RF Lambda
A Frequency Mixer is a 3-port electronic circuit that uses a diode network. It converts RF to a lower IF (or baseband signal) for easy signal processing in receivers. And it converts IF frequency (or baseband signal) to a higher IF or RF frequency for efficient transmission in transmitters. Two of the ports are input ports and the other port is an output port. The ideal Mixer mixes the 2 input signals such that the output signal frequency is either the sum (or difference frequency) of the inputs.
