Tunable vibration isolation system with integrated A-frame architecture for low phase noise radio frequency synthesizers

摘要

A radio frequency (RF) frequency synthesizer includes a chassis housing that holds components of the RF frequency synthesizer. The chassis housing is installable into an instrument cabinet. A pair of mounting brackets are connected to opposing interior sides of the chassis housing and receive an A-Frame assembly which supports vibration sensitive RF circuitry and RF components. The A-Frame assembly is attached to the pair of mounting brackets in the chassis housing and provide a spatial separation between the kinematic inputs and the vibration sensitive RF circuitry and RF components. The A-Frame assembly includes a folded sheet, the folded sheet defining an angle between a first planar region and a second planar region, and may include a planar frame cross-member attached to the first planar region and the second planar region, the planar frame cross-member spanning the angle between the first and second planar regions.
