Patent ID: 7668505

Claim:
A system comprising: an antenna; and a pre-select filter in signal communication with the antenna, the pre-select filter comprising: a plurality of subfilters configured to filter a received signal, each subfilter comprising: a first Micro-Electro-Mechanical Systems (MEMS) filter set comprising a first plurality of MEMS filters in parallel with each other and configured to filter the received signal at a first bandwidth; and a second MEMS filter set comprising a second plurality of MEMS filters in parallel with each other and configured to filter the signal filtered by the first MEMS filter set at a second bandwidth that is offset from the first bandwidth; wherein the plurality of MEMS filters in the second MEMS filter set are each directly coupled in series to a corresponding one of the plurality of MEMS filters in the first MEMS filter set in a one-to-one coupling relationship; and a switch coupled to each of the second plurality of MEMS filters, wherein the switch is activated based on a tuning signal received by the pre-select filter; an amplifier in signal communication with the pre-select filter; and an analog-to-digital converter in signal communication with and directly connected to the amplifier.
