Patent ID: 7668263

Claim:
A frequency synthesizer comprising: a voltage controlled oscillator which generates a signal; a first divider which divides a frequency of the signal generated by the voltage controlled oscillator by two to generate a first divided signal and a Q signal of the first divided signal; a second divider which divides a frequency of the signal generated by the voltage controlled oscillator by three to generate a second divided signal; a third divider which divides a frequency of the second divided signal by five to generate a third divided signal; a polyphase filter which adjusts a phase of the third divided signal to generate a quadrature (Q) signal of the third divided signal; and a single side band (SSB) mixer which generates a frequency synthesized signal having a frequency which is a frequency synthesis of the first divided signal and the third divided signal, from the first divided signal and the Q signal of the first divided signal, and the third divided signal and the Q signal of the third divided signal.
