The single conversion receiver includes: a first bandpass filter that lets only a desired band of a received RF signal pass through; a first mixer that converts the RF signal passing through the first bandpass filter into a first intermediate frequency signal; a second bandpass filter that lets only a band of a desired frequency channel of the first intermediate frequency signal pass through; a quadrature demodulator that converts the first intermediate frequency signal to baseband signals composed of an I phase and a Q phase; an oscillator that generates a first local signal 2^M times the center frequency of the second bandpass filter (where M is an integer); a fractional-N PLL frequency synthesizer that generates a second local signal with a frequency non-integer times the first local signal and supplies the second local signal to the first mixer; and a first frequency divider that divides the frequency of the first local signal by (2^M) to generate a third local signal and a fourth local signal having 90 degree phase difference from the third local signal, and supplies the third local signal and the fourth local signal to the quadrature demodulator."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Single conversion receiver and communication system including same","description":"There is provides a single conversion receiver and a communication system having wide occupied frequency bands and good receiving sensitivity.
