Temperature variable attenuator designed for high reliability, commercial applications

Fri, 09/14/2012 - 4:54pm

State of the Art (SOTA), Inc. introduces a new line of temperature variable attenuator (TVA) for both high reliability and commercial applications.

Available in a 1512 case size (.150" X .125" X .020") with single surface solderable or wire bondable terminations.

The attenuation of these TVA's decrease with increasing temperature allowing the TVA to passively compensate for the amplifier's drop in gain with temperature.This kind of signal compensation can be used for various amplifiers (power amplifiers, low noise amplifiers, MMIC amplifiers, and gain block amplifiers),circulators, mixers, power dividers, and other temperature sensitive devices. TVA's have the added benefit of lower signal distortion, phase change, and intermodulation compared to active circuit temperature compensation. These devices operate between DC and 6 GHz, with attenuation between 1-10 dB. They are offered in three temperature coefficient of attenuation (TCA) values -0.003, -0.007, and -0.009 dB/dB/C. The power handling capability is 2 watts with a 50 ohm load. High reliability and space screening is also available.
