摘要： A high throw-count multiple-pole FET-based RF switch architecture that provides good RF performance in terms of insertion loss, return loss, isolation, linearity, and power handling. A common port RFC is coupled along a common path to multiple ports RFn. Embodiments introduce additional common RF path branch isolation switches which are controlled by state dependent logic. The branch isolation switches help to isolate the unused branch ports RFn and the unused portion of the common path from the active portion of the common path, and thereby reduce the reactive load attributable to such branches that degrades RF performance of the ports RFn “closer” to the common port RFC. The branch isolation switches can also be used to reconfigure the switch architecture for a multiplex function as well as separate switch path banks for re-configurability of purpose, tuning, or varying switch throw counts and packaging options.

摘要： An electronic switch contains an input terminal, and output terminal and at least one first switch element, which provides a voltage-dependent characteristic. In this context, the first switch element connects the input terminal to the output terminal in a selective manner. The electronic switch further comprises a compensation element, which provides a voltage-dependent characteristic. In this context, the compensation element is arranged in such a manner that it at least partially compensates the frequency-dependent characteristic of the switch element.

摘要： An RF switch includes first, second and third transmission lines for forming ports, respectively, and first, second and third slot line pattern portions connected to one another, for transferring signals to the first, second and third transmission lines, respectively.

The second slot line pattern portion includes a loop slot line formed by a first and a second half loop slot line, a second sub-slot line for transferring a signal received from the connection point to the second transmission line through the loop slot line, and a switching circuit for shorting the gap of a corresponding slot line.
