Period Doubling and Subharmonic Generation in PIN Diode Control Circuits

Abstract

This paper describes work done in sub-harmonic signal generation through period doubling in a PIN diode switch circuit. The work compares simulations using a SPICE PIN diode model of period doubling with measurements in the high frequency range and shows good agreement between the measurements and simulations. Of note is the observation that the peak sub-harmonic signal is approximately 15 dBc the fundamental over an octave change in frequency.
