Abstract

We investigate the sensitivity and nonlinear properties of a tunnel diode microwave detector as functions of the input power and the load impedance presented at the detector's output. We compare the two-tone method estimate of nonlinearity with precise voltage-power measurements. Regression spline modeling of the voltage-power relationship is used to predict the actual received power, and hence the brightness temperature, at the detector.
