The PXV1220S series of thin film thermo-variable chip attenuator from Susumu are ideal for temperature drift compensation and provide 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 PXV series offers an attenuation range from 1dB up to 10dB with a a tolerance of ±0.5dB (@25°C, no load), power rating of 0.063W and an impedance value of 50Ω, all in a 0805 chip size.
