Radio circuits and components thereof including temperature responsive liquid MEMS

摘要

A radio circuit includes an adjustable RF front-end module on an IC die, a liquid MEMS component on a board, and a processing module on the IC die. The adjustable RF front-end module adjusts processing of an inbound or an outbound RF signal based on a compensation control signal. The liquid MEMS component changes an operational characteristic as temperature of the radio circuit varies. The processing module generates the compensation signal based on the changing of the operational characteristic of the liquid MEMS component. The liquid MEMS component includes a channel within the board, a liquid droplet contained within the channel, and one or more conductive elements proximal to the channel.

1. A radio circuit comprises:
an adjustable radio frequency (RF) front-end module on an integrated circuit (IC) die, wherein the adjustable RF front-end module adjusts processing of an inbound or an outbound RF signal based on a compensation signal; a liquid micro-electro-mechanical system (MEMS) component on a board, wherein the liquid MEMS component includes:
a channel within the board;a liquid droplet contained within the channel; andone or more conductive elements proximal to the channel, wherein, when temperature of the radio circuit varies, the liquid droplet changes with respect to the one or more conductive elements thereby changing an operational characteristic of the liquid MEMS component to produce at least one corresponding output signal that indicates an operating temperature of the radio circuit; and a processing module on the IC die, wherein the processing module is operable to receive the at least one corresponding output signal and to process the output signal to generate the compensation signal.
