Wide-Band Thermopads® WB2 Series

The WTVA WB2 is EMC’s wide band temperature variable attenuator and was designed for wire bondable applications. This product provides a good linear shift from DC to 20 GHz and from -55 °C to +125 °C. Our Thermopads® are microwave absorptive attenuators which provide power dissipation that varies with temperature. This product is available with bondable gold terminals and a wrap around ground plane.
