Liquid MEMS component and RF applications thereof

摘要

A radio circuit includes a front-end module, a board, a liquid MEMS component, and a coupling component. The front-end module is implemented on at least one integrated circuit (IC) die and includes a variable circuit. The variable circuit is adjustable to facilitate an operational adjustment of the front-end module for a given operational condition of the radio circuit. The board supports the liquid MEMS component and supports, at least indirectly, the at least one IC. The coupling component electrical couples the liquid MEMS component to the variable circuit, wherein, based on a control signal, one or more characteristics of the liquid MEMS component is changed, which adjusts the variable circuit.
