Patent ID: 8238839

Claim:
A receiver comprising: a low noise amplifier which amplifies received signals received via an antenna; a frequency divider which divides a frequency and generates a local signal; mixers which mix said local signal and an output of said low noise amplifier; programmable gain amplifiers which amplify outputs of said mixers; and a gain controller which controls said programmable gain amplifiers, wherein said frequency divider comprises a current amount adjustment means for adjusting the amount of currents to be output from its output terminals, wherein a gain controller control signal to control said programmable gain amplifiers is input to said gain controller, wherein said gain controller adjusts an amplification factor of said programmable gain amplifiers and the amount of currents to be output from the output terminals of said frequency divider according to the gain controller control signal, wherein said current amount adjustment means comprises emitter follower current circuits, and wherein a transmission mode flag signal is further input to the receiver and control of said frequency divider by said gain controller is deactivated when the transmission mode flag signal is negative.
