STUDY OF RECEIVER MIXER CHARACTERISTICS.
Abstract
Mixer phenomena and prediction techniques are reviewed in the light of advanced knowledge of nonlinear device characteristics. Measurement and analysis problems associated with the interdependence of mixer operating parameters are emphasized, and the inadequacies of current prediction schemes are discussed in relation to their application to operational receivers. Tests were performed to determine if the harmonic and response generating properties of nonlinear devices are functions of signal phase relationships. The measurement procedures and instrumentation necessary to measure such relationships are presented. Test results are shown which verify that variations in the phase relationships between the fundamental and harmonics of an injected signal cause radical variations in output harmonic and response levels. It is also shown that the phase of output responses are dependent upon mixer bias level. (Author)
