Abstract

A new frequency translation device test station, the Anritsu ME7810A, is introduced and used to examine conversion loss performance over frequency and power variation for two commercially available mixers. The station is first successfully benchmarked against more traditional general-purpose instruments, and then used to explore conversion loss measurements over various combinations of LO and RF signal frequency and power. Results from the new station are seen to compare well with conversion loss measurements made with a power meter, network analyzer and a spectrum analyzer. The automated calibration and measurement features of the test station allow rapid acquisition of power-meter referenced mixer measurements over a wide range of stimulus conditions. Examination of such measurements help to build a better understanding of the overall performance of a mixer's conversion loss behavior under varied LO/RF frequency and power conditions.
