摘要： A high-speed cross-point switch is built on a preferably silicon substrate and uses bipolar transistor switching elements. Preferably, the bipolar transistors are SiGe bipolar junction transistors. Intersecting conductive input and output microstrips are preferably thinned at their intersections to reduce shunt capacitance between the coupled lines. It is also preferred that the input buffer be connected in cascode fashion with the switching transistors in order to create an amplification stage. The signal and its inverse are carried on balanced microstrip pairs in order to reduce electromagnetic field strength at the center of the balanced line pairs thereby improving isolation between two crossing balanced pairs.

摘要： A sharp control voltage switch utilizing a plurality of field effect transistors (FETs) having and a bypass resistance topology to sharpen the control voltage. Utilizing a total of six gates allows the switch to operate at a low control voltage without the need to increase device periphery or die size. Feed-forward capacitors connected between the gate and source of an uppermost FET and the gate and drain of a lowermost FET are used to reduce signal distortion and improve the linearity and harmonic noise rejection characteristics of the FETs within the switch and thus lower the harmonics of the switch.

摘要： Several embodiments are shown for a quick connect/disconnect microwave coaxial connector which is held together under magnetic force. In one embodiment, the ends of coaxial cables are provided with annular magnets and the end faces ground flat. A good low SWR coaxial connection is made and held by simply pushing the ends together. In another embodiment, ring magnets are employed to hold standard coaxial ends together while enabling their disconnection by pulling them apart. A magnetic adapter is used to facilitate coaxial connections.
