Abstract
There are provided an A/D converting circuit () for converting, into a digital signal, a broadband intermediate frequency signal which is output from a frequency converting circuit (), and a DSP () for generating and outputting control data to control gains of an antenna damping circuit () and an LNA () based on a level of the broadband digital intermediate frequency signal which is output from the A/D converting circuit (), and the broadband intermediate frequency signal which is output from the frequency converting circuit () is A/D converted and supplied to the DSP (). Consequently, it is possible to reduce a frequency of a signal input to the A/D converting circuit (). Thus, it is also possible to reduce a consumed current without requiring the use a special AD converter corresponding to a radio frequency input.
