ABSTRACT:
A diode microwave switch is disclosed having both low power dissipation loss and a low voltage standing wave ratio by the techniques of mounting microwave diodes on pedestals and interconnecting them with air line microstrip connections and utilizing special impedance matching techniques. Voltage standing wave ratios of 1.15:1.00 with 0.3 db loss in a three diode 60 db isolation switch are readily obtained.
