Diode mount having integral resonant circuit
Abstract
Abstract A SEMOCONDUCTOR MOUNTING PACKAGE INCORPORATING ITS OWN RESONANT CIRCUIT IS DISCLOSED FOR MILLIMETER WAVEGUIDE USE. THE APPARATUS COMPRISES A METAL STUD HAVING TWO SPACED METAL PROJECTIONS FORMED ON ITS END SURFACE, A TWO-TERMINAL SEMICONDUCTOR DEVICE MOUNTED ON THE SURFACE BETWEEN THE PROJECTIONS, AND A METAL RIBBON CONNECTING THE UPPER DEVICE TERMINAL TO A SOURCE OF BIAS ENERGY. THE RIBBON, THE PROJECTIONS, THE STUD SURFACE, AND MEANS PROVIDING A LOW IMPEDANCE PATH FOR MILLIMETER WAVE ENERGY ACROSS THE GAPS BETWEEN THE RIBBON AND THE PROJECTIONS FORM A RESONATING LUMPED INDUCTANCE CAVITY AROUND THE DEVICE. THE IMPEDANCE OF THIS PACKAGED CIRCUIT IS OF RELATIVELY SIMPLE FORM, APPROXIMATELY OF A PARALLEL RESONANT CIRCUIT COMPRISING THE DEVICE AND THE LUMPED CAVITY INDUCTANCE. WITH ITS USE OSCILLATORS HAVE BEEN BUILT HAVING GOOD MODULATION SENSITIVITY AND FUNDAMENTAL FREQUENCIES IN THE RANGE OF 60 GHZ.
