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

An A-frame assembly for supporting vibration sensitive radio frequency (RF) components comprising:

• a first planar region;
• a second planar region, wherein at least one of the first planar region and the second planar region are configured to support at least one of the vibration sensitive RF components, and wherein the first planar region and the second planar region are in contact with one another along a common edge, the common edge defining an angle between the first planar region and the second planar region, and 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 planar region and the second planar region.

A method for tuning the spectral response of an assembly configured to support vibration sensitive radio frequency (RF) components, the assembly including a first planar region and a second planar region arranged with respect to one another to define an angle along a common edge of the first planar region and the second planar region, and a third planar region defining a frame cross member attached to the first planar region and the second planar region, the frame cross member spanning the angle defined between the first planar region and the second planar region, the method comprising the steps of:

• selecting a material for at least one of the first planar region, the second planar region and the third planar region, wherein the spectral response of the assembly is dependent at least in part on the selected material;
• and selecting a thickness of at least one of the first planar region, the second planar region and the third planar region, wherein the spectral response of the assembly is dependent at least in part on the selected thickness.
