rf Switching apparatus utilizing optical control signals to reduce spurious output |
摘要 |
An rf multiplexer includes a plurality of rf switch assemblies for switching a selected rf signal to an output in response to an optical control signal. Each rf switch assembly includes a switch circuit mounted in a conductive enclosure. The optical control signal from a control circuit is coupled by an optical fiber into the enclosure to an optical receiver which energizes a diode rf switch. Spurious conduction of rf signals along switch control lines is thereby eliminated without using filters. The multiplexer is particularly useful in a direct frequency synthesizer requiring high speed switching.
