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.

Variable frequency multiplier

Wire bonds connect current-carrying edges of high-frequency planar conductors to other electrical devices. In one embodiment, planar transmission lines are interconnected using two wire bonds. One bond wire extends from an edge of a first center conductor to a corresponding edge of a second center conductor, and a second bond wire extends from the other edge of the first center conductor to the other edge of the second center conductor. Embodiments include center conductors at different heights and having different widths, and different electrical devices, such as semiconductor integrated circuits. In a particular embodiment, ball bonding is used. In some embodiments, a tack bond is included after a ball bond to allow closer attachment of the bond wire to the edge of the conductor.

Electrical interconnection for high-frequency devices

An electrical interconnection includes a flex-circuit having a signal conductor and a shield conductor. A mating surface of the flex-circuit has a signal conductor portion surrounded by a shield conductor portion. The signal conductor portion is electrically coupled to the signal conductor and the shield conductor portion is electrically coupled to the shield conductor.
