Abstract
A single chip RF communication system and method is provided including a transmitter and a receiver. The RF communication system in accordance with the present invention includes an antenna for receiving transmitting RF signals, a PLL for generating multi-phase clock signals having a frequency different from a carrier frequency in response to the multi-phase clock signals and a reference signal having the carrier frequency, a demodulation-mixing unit for mixing the received RF signals with the multi-phase clock signals having the frequency different from the carrier frequency to output the RF signals having a frequency reduced by the carrier frequency and an A/D converting unit for converting the RF signals from the mixing unit into digital signals.
