Abstract
A comparative analysis of the operation of subharmonic mixers (SHMs) based on a resonant tunnel diode (RTD) and a Schottky-barrier diode (SBD) is performed. The dependences of the conversion loss of the RTD- and SBD-based SHMs on local-oscillator power are calculated. The SHM operation modes that allow the performance indices of the RTD-based mixer to be improved as compared to those of the SBD-based mixer are presented. The possibility of increasing the upper intermodulation-distortion dynamic-range limit of the RTD-based SHM as compared to that of the SBD-based SHM is theoretically shown and experimentally confirmed.
