Coaxial Relays

The high dielectric strength of a vacuum is one of the important features which distinguishes Jennings vacuum coaxial relays from other types of coaxial relays. The use of vacuum as a contact environment increases the operating reliability and the life of the relay. Absence of oxygen prevents contact corrosion and the formation of oxides and organic materials, which can increase circuit resistance. Jennings vacuum relays are distinguished by very low thermal and RF noise generation. Because the contact resistance of vacuum coaxial relays is very low and stable, these units offer very low circuit losses. RF insertion loss is typically between 0.02 and 0.1 dB at operating frequencies.

Some of our most common applications are:
  • High speed antennae switching
  • Transmit-receive switching
  • Crossbar matrices
  • CCTV, CATV
  • Microwave telemetry data acquisition links
  • Coaxial instrumentation
Jennings coaxial relays feature:
  • Long life, high reliability
  • High speed switching
  • Low, stable contact resistance
  • Maintenance free operation
  • Compact size for applications with space/weight limitations
  • Application flexibility
