Abstract: RF attenuator circuitry includes an RF attenuator and a control system. The RF attenuator is configured to provide an attenuation response between an input node and an output node. The control system is coupled to the RF attenuator and configured to adjust one or more control signals provided to the RF attenuator based on either the temperature of the circuitry or an externally applied test signal provided to the control system. The control signals are provided such that the attenuation response of the RF attenuator is substantially linear-in-dB with respect to either the temperature or the test signal provided to the control system. Because the control system is configured to adjust the control signals based either on a temperature of the circuitry or the test signal, the response of the RF attenuator can be easily and quickly tested to ensure linear-in-dB operation thereof.
