Abstract
Methods and systems for a programmable LO generator utilizing a DDFS for extremely high frequencies are disclosed. Aspects of one method may include generating a first signal and a second signal using a base signal. The DDFS may generate the first signal, where the base signal may be divided down to provide a reference clock for the DDFS. The base signal may be divided to a lower frequency to generate the second signal. The first and second signals may be mixed to generate a third signal, which may be, for example, bandpass filtered to generate a local oscillator signal. Accordingly, the local oscillator signal, which may comprise I and Q components, may range to EHS band frequencies.
