摘要： An adjustable filter is responsive to a control signal to change a frequency response of the adjustable filter based on at least one of a geographic location, frequency spectrum information, and a status of a secondary internal radio. The control signal may shift a center of the pass band from a first center frequency to a second center frequency and/or change a pass band bandwidth from a first bandwidth to a second bandwidth. A transmitter includes an adjustable filter responsive to a control signal and controller configured to select a frequency response of the adjustable filter by generating the control signal based on a geographical location. In one aspect, the geographical location indicates a region of operation of the receiver and the frequency response is selected in accordance with the region.

摘要： A controllable filter arrangement with a voltage controlled device that subjects a signal to a predetermined impedance as part of the filtering process when the voltage controlled device is in an active state. In an inactive state, the voltage controlled device may subject the signal to an impedance that prevents all frequencies of the signal from passing. This configuration may advantageously increase frequency selectivity and reduce insertion loss, size, cost, and tuning complexity when compared with conventional filter designs.

摘要： The present invention provides a phase shifting filter and a phase compensating direct downconversion receiver. A DC offset detector detects a DC offset in a received baseband signal and provides a feedback signal. A tunable filter phase shifts a local oscillator signal responsive to the feedback signal. The phase-shifted local oscillator signal is used to directly downconvert a received RF signal, whereby DC offset in the resulting baseband signal is reduced.
