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 ...
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 ...
(Nanowerk News) In a just-published work in the magazine Science ("Wafer-Scale Graphene Integrated Circuit"), IBM researchers announced the first integrated circuit fabricated from wafer-size graphene ...
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 ...
