Patent ID: 7764934

Claim:
A transmitter, comprising: a frequency synthesizer coupled to receive outbound transmit data and operable to modulate the outbound transmit data to produce a modulated RF signal; and a power amplifier coupled to the frequency synthesizer and operable to amplify the modulated RF signal to produce an outbound RF signal, wherein the frequency synthesizer further includes: a digital processor coupled to receive the outbound transmit data and operable to modulate the outbound transmit data to produce a modulated digital signal; a Digital-to-Analog Converter (DAC) coupled to receive the modulated digital signal and operable to convert the modulated digital signal to a modulated analog signal; a low pass filter coupled to receive the modulated analog signal and operable to filter the analog signal to produce a filtered modulated analog signal; and a phase locked loop coupled to receive the filtered modulated analog signal to up-convert the filtered modulated analog signal to the modulated RF signal.
