26 Jan 1972TL;DR: In this paper, a solid-state switching circuit for use in the Ka frequency band is disclosed wherein a body casting which a waveguide passageway therethrough includes one or more packaged PIN diodes in shunt across a reduced height portion of said waveguide.
Abstract: A solid-state switching circuit for use in the Ka frequency band is disclosed wherein a body casting which a waveguide passageway therethrough includes one or more packaged PIN diodes in shunt across a reduced height portion of said waveguide. A quarter wavelength bias rod engages the PIN diode package at one terminal and a tuning screw engages the PIN diode package at the other terminal, the tuning screw being turnable into and out of the waveguide.
