摘要： A reconfigurable RF transceiver for use in either a base station or a mobile station Of a wireless network. The reconfigurable RF transceiver comprises a first receive path that down-converts an incoming RF signal to analog and digital baseband signals. The first receive path in a first mode down-converts the incoming RF signal in a receive frequency band for the base station and in a second mode down-converts the incoming RF signal in a receive frequency band for the mobile station. The reconfigurable RF transceiver further comprises a transmit path for up-converting an outgoing baseband signal to an outgoing RF signal. The transmit path in the first mode up-converts the outgoing baseband signal in a transmit frequency band for the base station and in the second mode up-converts the outgoing baseband signal in a transmit frequency band for the mobile station.

摘要： A wireless receiver is provided that includes a multi-step gain-control low-noise amplifier (LNA) stage and a mixer stage. The LNA stage is operable to amplify at least one input signal to generate at least one LNA output. The mixer stage is directly coupled to the LNA stage (without an intervening external bandpass filter) and is operable to down-convert the LNA output to generate a mixer output.

摘要： An apparatus and method manage impedance values in a radio in a wireless network. The apparatus includes a tunable matching network (TMN) positioned on a path between a transceiver and an antenna. The TMN includes a plurality of immittance elements. A voltage standing wave ratio (VSWR) detector is configured to detect a ratio of a signal passing the VSWR detector and a signal reflected from the TMN. A control circuit is configured to identify an operating setting for the radio, set a number of the immittance elements based on the operating setting, monitor the ratio detected by the VSWR detector, and modify a setting of at least one of the immittance elements based on the ratio detected.

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.
