A micro-electro-mechanical system (MEMS) transfer switch is disclosed. The transfer switch comprises a single-pole, N-throw switch section having N selectable switches. Each selectable switch of the N selectable switches has an input, a control terminal and an output. An electrically conductive line is coupled to each of the selectable switches of the N selectable switches. The transfer switch includes a single-pole, M-throw switch section having M selectable switches coupled to the conductive line, each selectable switch of the M selectable switches having an output, a control terminal and an input. The single-pole, N-throw switch section and the single-pole, M-throw switch section are packaged in a single micro-electro-mechanical system (MEMS) die. The N and M are numbers between two and eight and the N selectable switches and the M selectable switches are different switches.

Configurable micro-electro-mechanical systems (MEMS) transfer switch and methods

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.

Sensitivity radio frequency (RF) receiver front-end using MEMS switches, RF communications device and method

A photon conversion assembly. A first filter assembly is configured to transmit photons in at least one received band in a downstream direction of an optical pathway and to reflect photons in at least one converted band that are moving in an upstream direction of the optical pathway. A photon conversion material has a first side and a second side. The first side is downstream of the first filter assembly, and the second side is upstream of a second filter assembly. The photon conversion material is configured to convert photons in at least one received band to photons in at least one converted band. A second filter assembly is configured to transmit photons in the at least one converted band in a downstream direction of the optical pathway and to reflect photons in the at least one received band that are moving in the downstream direction of the optical pathway.
