Abstract
In the design of microwave switches — where the diode control element is expected to switch between nearly open and nearly short circuit impedances — it would seem that only the use of packageless diodes is practical since the parasitic inductance and capacitance associated with diode packages cannot help but have an adverse effect on switching performance. Though this observation is correct, packaged diodes offer many advantages. Switches can be built with replaceable diode sockets, permitting simple maintenance; packaged diodes can be used, eliminating the need for the skilled labor required for chip assembly. The interchange-ability of diodes in packaged form affords the possibility of special fine tuning which is impractical with diode chips that are soldered or bonded into the switch device.
