QSC Series Coax PIN Switches

Characteristics
  • Fullband Operation
  • Fast Switching Speed
  • High Isolation
Product Description

QuinStar Technology's QSC series coaxial PIN switches provide fast, high isolation and low insertion loss switching over the full K- and Ka- frequency bands. They are available in SPST and SPDT configurations and feature a compact package that incorporates the driver circuitry.

Standard input/output RF ports are K-female connectors, and DC bias/control signal is via feedthrough pins. These switches are well suited for pulse modulation and receiver protection in broadband systems utilizing coaxial components.
