A 7-Gc/s Narrow-Band Waveguide Switch Using p-i-n Junction Diodes

A narrow-band waveguide switch with power capability in excess of 8 watts has been designed in WR137 waveguide. j-i-n diodes are used in band elimination filter sections. the attenuation in the reject band is greater than 80 dB over a 10 Mc/s range, and the passband loss is less than 0.5 dB.
