Abstract:
An RF signal switch circuit that allows connection of any of N radio frequency (RF) input terminals to a switch output port, either in a low loss mode, in a bypass mode, or, optionally, in a signal function mode. Embodiments of the invention allow for both a single switch in the series input path to a target circuit while still having the ability to isolate the bypass path from the target circuit. In the low loss and bypass mode, the circuit simultaneously exhibits low input insertion loss (and thus a low noise factor) and high bypass mode isolation.

Claim (Index 15):
A method of switching radio frequency (RF) signals, including:\n (a) providing at least one first type RF signal port, each first type RF signal port having:\n (1) a first shunt switch coupled to the first type RF signal port and configured to selectively couple the first type RF signal port to circuit ground, \n (2) a first series switch coupled between the first type RF signal port and configured to be coupled to at least one corresponding target circuit, and \n (3) at least one set of second series switches coupled to the first type RF signal port; \n (b) coupling at least one first circuit path to a corresponding second shunt switch and coupled to a corresponding one set of second series switches, each first circuit path being configured to be coupled to at least one signal function circuit; (c) providing at least one second circuit path configured to be coupled to the at least one signal function circuit, and being coupled to a corresponding third shunt switch; (d) coupling at least one third series switch to a corresponding one second circuit path and to at least one first series switch; (e) providing at least one second type RF signal port; and (f) coupling a switching network to the at least one second type RF signal port, the switching network including:\n (1) at least one first switch path each having a series switch coupled to at least one second type RF signal port and configured to be coupled to one corresponding target circuit, and a shunt switch coupled to a node between such series switch and such corresponding target circuit and configured to selectively couple that node to circuit ground, and \n (2) at least one second switch path each having a first series switch coupled to the at least one second type RF signal port, a second series switch coupled to the first series switch and to at least one second circuit path, and a shunt switch coupled to a node between the first and second series switches and configured to selectively couple that node to circuit ground.
