Frequency upconversion/downconversion and frequency multiplication/division is a critical feature of many RF circuits. The basis for superheterodyne communications is the generation of a baseband or intermediate frequency (IF) signal and the use of upconversion to...
Frequency Downconverter, upconverter, multiplier, divider, mixer, or frequency translator? What is an RF Mixer?
Not to be confused with awkward socials at microwave industry events, RF Mixers are fundamental building blocks of many RF circuits and systems. The basic function of a RF mixer is frequency translation. Frequency translation shifts the frequency content of a signal,...
RF Active Mixers Versus Passive Mixers
RF mixers are frequency conversion devices that are composed of nonlinear elements that allow for frequency “mixing” of RF, intermediate frequency (IF), and local oscillator (LO) signals. There are two main functions of RF mixers: either upconversion or...
RF Component & Device Test Series: RF Mixer Testing
Key Mixer Performance Parameters RF Mixers are 3-port frequency translation circuits that “mix” the signal inputs from two of its ports and outputs a third signal, along with other products, that is a function of the two inputs. We offer a variety of...
