RF Mixers

RF mixers combine RF and LO signals to create sum and difference frequency products for upconversion, downconversion and test translation. They are used in receivers, transmitters, radar channels, spectrum equipment and microwave instruments.

RF Frequency Conversion EngineeringHow to Plan RF, LO and IF Frequencies for an Upconverter or Downconverter

A practical method for turning RF input, desired output and bandwidth requirements into an RF/LO/IF plan with controlled images, spurs, leakage, gain, noise and linearity.

FAQ

How do LO drive level and LO leakage affect RF converter performance?

LO drive sets the mixer switching condition and therefore influences conversion response, compression and intermodulation, while LO leakage can disturb antennas, ADCs, amplifiers and adjacent channels.

What is the image response in an RF frequency converter, and how should it be controlled?

An image is an undesired input frequency that produces the same wanted IF through another valid mixing relationship; control it with frequency planning, preselection and verified image or IQ rejection.

RF mixers

RF mixers use a nonlinear mixing element to combine an RF signal with a local oscillator signal and produce sum and difference frequency components. They can be used as the core conversion element inside receivers, transmitters, converters and measurement systems.

RF, LO and IF port behavior

Important data includes RF frequency range, LO frequency range, IF range, conversion loss or gain, LO drive level, port isolation, input compression, IP3, noise behavior, spurious response, impedance and package or connector format. These values shape image response, dynamic range and unwanted products in radar, communication, spectrum monitoring and RF test equipment.
