A variable frequency multiplier circuit for frequency multiplying an input signal provided by an ultra-low phase noise signal source includes a tone generator configured to generate a multiple tones from the input signal; a signal separating circuit configured to separate the multiple tones into tones of interest and idler tones, where the tones of interest are separated into one or more groups and outputted from the signal separating circuit, and the idler tones are terminated; an amplification circuit configured to amplify each group of the tones of interest to optimize small and large signal responses; and a switched filter bank configured to selectively connect a selected tone from the tones of interest to a circuit output.

A method of assembling a fully detachable microcircuit starts with obtaining a fabricated microcircuit housing with an upper surface, a lower surface, a first recess in the upper surface, a second recess in the lower surface, and a pin on the lower surface. A thermal layer is applied to the lower surface. A conductive elastomer signal pin connector and a ground pin connector are attached to a thin film circuit, and the thin film circuit with is inserted into the second recess with the conductive elastomer signal pin connector and the ground pin connector attached. A bonding target is applied to the upper surface. The bonding target and the microcircuit are connected with a bond wire. The microcircuit housing is screwed to a printed circuit assembly without bonding the microcircuit housing to the printed circuit assembly.
