Abstract
A temperature controlled attenuator circuit is disclosed. The temperature controlled attenuator circuit comprises a temperature sensor circuit for sensing the temperature of an electronic component and generating a control voltage inversely proportional to a difference in temperature between an ambient temperature and the temperature of the electronic component and a variable attenuator circuit configured to vary its attenuation based upon the control voltage to provide an attenuation based upon the difference in temperature between the ambient temperature and the temperature of the electronic component. A radio frequency module and wireless device comprising said temperature controlled attenuator circuit are also provided.
