Frequency mixers are often implemented using a diode bridge or a Gilbert cell. Both types of mixers use a local oscillator (LO) to flip the polarity of the radio-frequency (RF) input. When the LO is ...
The following is excerpted from Chapter 8 of “RF Circuit Design, 2e” by Christopher Bowick. Moving up the scale in complexity, we come to the next evolutionary RF architecture: the ...
