Abstract:
A transceiver comprising:a receiver including a first voltage controlled oscillator (VCO), first and second dividers connected to an output of said first VCO, a first mixer receiving an output signal of said first divider and a first RF signal, and a second mixer receiving an output signal of said second divider and a second RF signal; and a transmitter including a third divider, connected to the output of said first VCO, having means for switching a first division ratio and a second division ratio, a second VCO, a fourth divider, connected to an output of said second VCO, having means for switching a third division ratio and a fourth division ratio, a third mixer receiving an output signal of said fourth divider and a baseband signal, and a frequency conversion circuit for converting the frequency of an output signal of said third mixer using an output signal of said third divider.
