US 2019/0173466 A1 · Reconfigurable RF Switch using Single or Multiple-Pole, Single or Multiple-Throw Switches

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.

Dependent claims

A reconfigurable RF switch comprising a plurality of single-pole N-throw (SPNT) switches, wherein:

the reconfigurable RF switch is implemented on a single die;
all poles and throws of the plurality of SPNT switches are configured to be connected externally with respect to the single die;
N is an integer equal to or greater than 1;
the plurality of SPNT switches are separate with no interconnection within the single die, and
using a subset of or all of the SPNT switches of the plurality of SPNT switches, the reconfigurable RF switch is reconfigurable to operate as one or more of a) a plurality of single-pole, single-throw switches, b) a plurality of multiple-pole, multiple-throw switches and c) a combination thereof.
