Paper Abstract

We designed a simple heterodyne system for frequency domain photodetector characterization which is intended to avoid many of the disadvantages of earlier characterization systems and to minimize errors due to intensity fluctuation, frequency calibration, and source impedance mismatch without using vector network analysis. A detailed uncertainty analysis for the system indicates 95% confidence intervals between +/- 0.25 and +/- 0.6 dB at 25 GHz, depending on the photodetector output impedance.
