The PAV3137S series of thin film thermo-variable chip attenuators from Susumu are used for temperature drift compensation which provides an elegant solution to compensate for GaAs amplifier temperature drift, enabling the designer to discard the use of an automatic gain control (AGC) circuit on their PCB. The Susumu PAV series of thermo-variable attenuator offers an attenuation which varies with temperature, making it an ideal solution for correcting gain shift from temperature fluctuations with GaAs amplifiers.
