AN208: Microwave Receiver Linearity Verification

GENEVA, OH, October 10, 2015

The linearity of an RF or microwave receiver is typically measured at its intermediate frequency. Nonlinearities at high signal levels due to mixer compression, and at low levels due to noise, are then specified as maximum error figures. This application note shows how linearity can be measured over a frequency range of 100kHz to 40GHz using a precision power meter and RF power standards.
