WTVA Series Temperature Variable Attenuators
The WTVA is Smiths Interconnect|EMC's wide band temperature variable attenuator. This product provides a good linear shift from DC to 20 GHz and from -55 deg C to +125 deg C. Smiths Interconnect|EMC's Thermopads are microwave absorptive attenuators which provide power dissipation that varies with temperature. They are used to correct gain variations in amplifiers and other active components which tend to have gain anomalies over temperature. The WB2 style uses thick film gold wire bondable terminals. For RoHS compliant versions contact our factory. The WTVA is the preferred version of Smiths Interconnect|EMC's Thermopad for use in satellite communications, broadband EW applications, and for high frequency and broadband amplifiers.
