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.

Abstract: A circuit architecture and process that provides for a dual-mode methodology for an RF integrated circuit (IC) switch circuit that allows switching between a direct mapping configuration and a fully decoded mapping configuration, and further provides for changing either mapping configuration after fabrication. A control word is selectively compared to a programmed map register value so that, in a first mode, only one bit position of a control word matches a decoded programmed map bit pattern, and in a second mode, all bits of a control word match a corresponding programmed map bit pattern. Because the map registers can be programmed at least once after IC fabrication, the exact mapping required for a particular application can be determined post fabrication. Further, the first mode of operation is often beneficial during testing because multiple RF signal paths can be turned on at the same time and thus tested in parallel.

Abstract: Methods and devices taught in the present disclosure address the need for reconfigurable multi-pole multi-throw switches for various RF applications having different design requirements. Such reconfigurable switches can be reused for different applications without having to go through long research, development and manufacturing cycles. Design of multi-pole multiple switches with improved performance metric such as insertion loss, parasitic capacitance and bandwidth is also made possible using the teachings of the disclosure.
