Abstract
A radio frequency (RF) receiver includes an oscillator for outputting an oscillation signal from an output port thereof, a limiter for dividing the oscillation signal output from the oscillator into a branch signal at a predetermined dividing ratio outputting the branch signal, an amplifier for amplifying the branch signal output from the limiter, a frequency multiplier for outputting a local oscillation signal having a frequency obtained by multiplying a frequency of the amplified signal by a predetermined multiplicand, a mixer for mixing the local oscillation signal and a signal supplied from an antenna, a band-pass filter for receiving a signal output from the mixer and outputting an intermediate frequency (IF) signal, a detector for producing a detected signal by detecting the IF signal, and a controller connected directly with the output port of the oscillator for performing an operation according to the detected signal based on the oscillation signal as a clock signal. This RF receiver can be inexpensive.
