摘要： A high isolation RF switch for launching a selected one of two RF signals into a slabline transmission line structure has a three switch configuration—a pair of input switches coupled to corresponding input ports and a transition switch coupled to an output port via a slabline transmission line. The input switches select one of the input ports for coupling to the transition switch, and the transition switch couples the selected input port from the input switches to the output port. A grounded conductor is situated between the input ports in a cavity of a housing within which the high isolation RF switch is located to provide isolation between the input ports. Additional isolation between the input ports is provided by coupling the non-selected RF signal to ground, either by grounding the non-selected input to the transition switch or the non-selected input port.

摘要： A deskew fixture has a multilayer circuit board from which pairs of mirrored signal launch contact extend from both sides of the circuit board. One pair of contacts is coupled to electrical ground and the other pair is connected via equal length, electromagnetically coupled strip lines to a signal source. Probe holders are mounted on the circuit boards to support measurement probes with the probing contacts of the measurement probes coupled to the signal launch contacts. Additional pairs of signal launch contacts may be provided with one pair receiving a positive signal from the signal source and another pair receiving a negative signal via equal length, electromagnetically coupled strip lines from the signal source for deskewing differential measurement probes.
