Abstract
A radio frequency transceiver includes a mixer circuit configured to convert an intermediate frequency signal into a radio frequency signal, a driver amplifier circuit configured to amplify the radio frequency signal from the mixer circuit, a temperature sensing circuit configured for sensing ambient temperature, and an attenuation circuit connected with the temperature sensing circuit, configured to decreasingly attenuate the radio frequency signal from the driver amplifier circuit as the ambient temperature increases.
