Garches, France — The 50-ohm PE4150 quad MOSFET mixer, from Peregrine Semiconductor, is ideal for designs requiring low conversion loss and high linearity such as portable radios operating in bands ...

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 ...
