Standard models are available in SPST and SPDT configurations with other configurations up to SP8T available on request. The switches provide an isolation of up to 50 dB with an insertion loss of less than 2.5 dB and a switching speed of 5 ns.
They are available in a compact connectorized package that incorporates the driver circuitry. The switches are ideally suited for pulse modulation and receiver protection in broadband systems that utilize coaxial components.
