Abstract:
1. An integrated circuit digitizing analog front end (DAFE) for a receiver, comprising: a substrate; a low noise amplifier (LNA) on the substrate; an analog-to-digital converter (ADC) on the substrate; a plurality of micro electro mechanical system (MEMS) switches on the substrate, wherein each of the plurality of MEMS switches comprise at least one pole operative to positively couple and decouple an input of the MEMS switch to an output of the MEMS switch; at least one anti-alias filter on the substrate; and at least one and-jam filter on the substrate; wherein the filter characteristics of the at least one anti-jam filter and/or the at least one anti-alias filter are changed using at least one of the plurality MEMS switches.
