|20140052399||FREQUENCY DETERMINATION CIRCUIT AND METHOD - Circuits and methods for identifying or verifying frequencies are disclosed herein. A frequency verification circuit comprises: an input port for receiving an input signal; a phase frequency difference detector for determining a difference in phase and frequency between the input signal and a feedback signal and for providing a control signal based on the detected difference; a voltage controlled crystal oscillator for producing an output signal based on the control signal; and a feedback loop including a feedback divider for frequency dividing the output signal by a factor R to produce the feedback signal, the feedback divider being programmable to a plurality of values of the factor R to correspond to a plurality of different test frequencies.||02-20-2014|
|20140015572||ULTRA LOW PHASE NOISE SIGNAL SOURCE - An apparatus and method for providing an output signal. The apparatus comprises an input for receiving a reference signal, an oscillator for providing an output signal, and an offset signal generator for frequency multiplying the reference signal to generate an offset signal that has a plurality of frequency products in a plurality of frequency bands. The apparatus further includes a mixer for mixing the offset signal with the output signal to produce a combined signal, an offset frequency selector for controllably selecting a frequency band of the offset signal, and a difference detector for detecting a difference between the reference signal and the combined signal and for providing a control signal to the oscillator based on the detected difference.||01-16-2014|
