Environmental effects on the Thermal Resistance of Varactor Diodes

For harmonic generation and pulse forming a fast rising waveform rich in harmonics is needed. This characteristic is provided by a step recovery diode (SRD).This paper presents design theory and fabrication steps for the SRD using epitaxial mesa structure. The diodes fabricated show breakdown voltages in the range of 60–80 volts with a ‘punch-through’ at 5 volts. The storage time and transition time of the diodes are 20 and 5 ns respectively. The ‘pill-with-prongs’ type case has been used for housing the diodes.
