    摘要: An apparatus and method amplify a signal for use in a wireless network. The apparatus includes a power amplifier, an envelope modulator, a tunable matching network (TMN), and a controller. The power amplifier outputs the signal at an output power. The envelope modulator controls a bias setting for the power amplifier. The TMN includes a plurality of immittance elements. The controller is operably connected the envelope modulator and the TMN. The controller identifies a desired value for the output power of the power amplifier, controls the output power of the power amplifier by modifying the bias setting of the power amplifier, and sets a number of the plurality of immittance elements based on the bias setting of the power amplifier.

    摘要: A lockable MEMS switching architecture provided having a clutch assembly, a switching member, and an actuator. The clutch assembly has one or more engagement features located in proximity to the switching member - particularly one or more receiving features located upon the switching member. The clutch assembly is actuated to disengage the engagement features from the receiving features. The switching member is actuated to move in relation to the clutch assembly. Once the switching member is in a desired position, the clutch assembly is de-actuated, causing the engagement features to re-engage with the switching member, thereby restricting its further movement.
