摘要

American Electronic Laboratories, Inc., Colmar, Pa., ATC RADAR BEACON SLS CRYSTAL DIODE SWITCH FAA/ARDS Type 108-2-2, 30 September 1963, 30 pp., Including 10 illus. Project No. 108-2D, Final Report (Contract No. ARDS-464).nThis report describes the development of a crystal diode microwave switch with coaxial input and output connectors. The switch was designed for alternately switching the RF output pulses of an ATC Radar Beacon System transmitter from a rotating directional' antenna to an omnidirectional antenna. The switch is a fast-acting solid-state switch that has relatively high power handling capability, low insertion loss and high isolation between the output channels. The solid-state switch driver is also described. The switch meets all design specifications. Field re placement of crystal diodes is not recommended in the model delivered but should be a design goal for future production model switches. The acceptance test procedure and test results are included.
