ABSTRACT:
Aspects of a method and system for transmission and/or reception of signals utilizing a delay circuit and a DDFS are provided. In this regard, a first signal may be delayed by 90°, via a plurality of delay elements and variable capacitance, to generate a second signal. The first and second signal may be mixed to generate a first LO signal, which may be utilized for a first frequency conversion. A second LO signal may be generated via a DDFS and may be utilized for a second frequency conversion. A digital input word of the DDFS, a value of the variable capacitance, and/or at least a portion of the delay elements, may be programmatically controlled based on a desired frequency for transmission and/or desired frequency for reception. The first frequency conversions may be up-conversions and/or down-conversions to/from baseband, one or more intermediate frequencies, and/or RF.
