A frequency scalable, low self-generated noise frequency source generates coherent or mostly-coherent local oscillator signals and includes a common reference, a coherent set of high frequency references and specific local oscillators which may be non-coherent for each specific output frequency. Delay lines may be included in the paths to ensure time delay alignment. The use of these elements with this modular design allows the generation of multiple coherent local oscillators via replication of the modular design elements.

Frequency scalable, low self-generated noise frequency source

A technique for providing secondary DC power to certain satellite payload components to reduce the number of secondary power converters on the satellite. A frequency generator ( ) is used as a source of secondary DC power instead of providing separate secondary DC power converters. A plurality of secondary DC power lines is tapped off of the frequency generator ( ) and applied to certain satellite payload components, such as LNA/DCs ( ) and upconverters ( ). Additionally, the secondary DC power available from the frequency generator ( ) is used as a secondary DC power source for a satellite beacon assembly ( ) that provides a signal to a beacon antenna ( ).
