Surface Mount Temperature Variable Attenuators

Temperature Variable Attenuators (TVA) passively compensate the output of temperature sensitive components (amplifiers, mixers, directional couplers, etc.) without distorting signal. Attenuation factor decreases with increasing ambient temperature but the attenuation factor changes at different rates above and below room temperature (see attenuation vs. temperature plot). An output tuned for temperatures above room temperature will perform poorly at temperatures below room temperature. Our enhanced Temperature Variable Attenuators (ETVA) provide a linear response over the entire -55°c to 125°c temperature range allowing designers to use a single compensation solution without compromising performance.

The planar terminations of the A termination type minimize inductive losses at higher frequencies (>4 GHz) when the device is flip chip soldered (film side down).
