Abstract
A radio frequency (RF) front end device is disclosed. The device comprises a plurality of micro-electro-mechanical system (MEMS) transfer switches having a plurality of parallel switch inputs and parallel switch outputs. The device comprises a plurality of banks of a plurality of parallel signal conditioning devices and each bank comprising a plurality of parallel paths having an input side and an output side, at least two of the banks of the plurality of signal conditioning devices couple the input side to the plurality of parallel switch outputs of a preceding MEMS transfer switch and the output side to the plurality of parallel switch inputs of a succeeding MEMS transfer switch. The MEMS transfer switches are controlled to condition a wideband signal through a selected set of signal conditioning devices to improve selection sensitivity of at least one frequency in a wideband. A method and RF communications device are also disclosed.
