| GaAs SPDT Reflective Switch, DC - 3 GHz with TTL/CMOS Control Input V 3.00 SW-312 Features n Integral TTL Driver n Ultra Low Power Consumption n Fast Switching Speed: 7 ns Typical n Surface Mount Package n 50 Ohm Nominal Impedance n MIL-STD-883 Screening Available CR-9 Description M/A-COM's SW-312 is a GaAs FET SPDT reflective switch with integral silicon ASIC driver. Packaged in a 16-lead ceramic surface mount package, this device offers excellent performance and repeatability from DC to 3 GHz while maintaining low power consumption. The SW-312 is ideally suited for use where fast speed, low power consumption and broadband applications are required. MIL-STD-883 screening available.
