Abstract
A radio communications deviceincluding a processorhaving a digital signal processor (DSP) coupled to a transceiverThe transceiver includes a digital-to-phase synthesizer having one or more independently variable frequency or phase signal outputs coupled to a transmitter and/or to a receiver. The variable frequency and phase outputs of the digital-to phase synthesizer are mixed with corresponding received signals and are capable of frequency or phase modulating information signals for transmission. Amplitude modulated signals may be provided through polar modulation by combining synthesizer outputs at a summer.
