QuinStar Technology’s series QSC coaxial PIN switches provide fast switching with high isolation and low insertion loss over the full K and Ka frequency bands. Standard models are available in SPST and SPDT configurations and feature a compact package that incorporates the driver circuitry. Switches with multiple throws (up to SP8T) are offered as custom products. Several versions of these switches are offered to suit a wide range of applications. SPST switches are offered in reflective and non-reflective versions. All switches are offered with a choice of either low insertion loss version or high isolation version. Control signal required to operate these switches is TTL.
Standard input/output RF ports are K-female connectors, and DC bias/control signal is via feedthrough pins. For high speed versions, SMA connector is provided for control signal. These switches are ideally suited for pulse modulation and receiver protection in broadband systems that utilize coaxial components.
