摘要： An amplifier provides two or more selectively enabled amplifier segments allowing a source signal to be amplified with a selectable output power. A bias circuit responsive to a bias control signal enables selectable combinations of one or more amplifier segments, thus allowing selection of a desired output power. Selecting a desired output signal power via the bias control signal corresponds to selecting an overall amplifier quiescent current that decreases with decreasing output signal power. Thus, the amplifier permits a controlling system, such as a mobile terminal (e.g., cellular telephone) to amplify a transmit signal with a selectable transmit signal output power and corresponding level of amplifier quiescent power consumption. Preferably, each segment comprises one or more transistor amplification stages which, when enabled by the bias circuit, are biased to permit maximum power linear amplification for the transmit signal.

摘要： The present invention relates to a process for implementing a base circuit design with configurable modifications to compensate for variations in component parameters due to material or processing characteristics. During the fabrication process, the base circuit is electrically tested to determine the characteristics of the base circuit given the materials and processes used to implement the circuit. Based on the testing, subsequent processing steps are used to modify the base circuit as necessary to compensate for variations in the circuit or component parameters due to the material or processing characteristics. Preferably, the base circuit includes hetero-junction bipolar transistors and the in-process testing is used to determine an associated beta value for the transistor. Based upon the determined beta value, the circuit is modified during processing to insure proper quiescent currents occur during normal operation given the beta of the transistor. Preferably, a top level mask is used to select the resistance in the base current path to select the proper base current for a desired quiescent collector current.

摘要： Pilot switch circuitry coupled across first and second terminals of a microelectromechanical system (MEMS) switch is provided to reduce or eliminate arcing between a cantilever contact and a terminal contact when the MEMS switch is opened or closed. The pilot switch circuitry establishes a common potential at the first and second terminals prior to, and preferably until, the cantilever contact and terminal contact come into contact with one another when the MEMS switch is closed. The pilot switch circuitry may also establish a common potential at the first and second terminals prior to, and preferably after, the cantilever contact and terminal contact separate from one another when the MEMS switch is opened.

摘要： The present invention is an RF cancellation circuit located between the output of a power amplifier and downstream circuitry, such as a transmitting antenna. The RF cancellation circuit cancels reflections resulting from antenna impedance mismatches, thereby presenting a constant load impedance to the output of the power amplifier. The RF cancellation circuit extracts a portion of the reflected signal, phase-shifts by 180 degrees and amplifies the extracted portion of the reflected signal to create a cancellation signal, and then cancels the balance of the reflected signal by adding in the cancellation signal. Directional circuitry is used to process the reflected signals without interfering with normal transmitted signals. Presenting a constant load impedance to the output of the power amplifier helps facilitate compliance with total radiated power into load mismatch specifications.

摘要： A system is provided for adjusting an output power of a multi-stage power amplifier by controlling a supply voltage provided to one or more output amplifier stages of the power amplifier using a switching DC—DC converter. In general, the system includes a power amplifier including an input amplifier stage and one or more output amplifier stages coupled in series with the input amplifier stage. The one or more output amplifier stages receive a variable supply voltage from switching DC—DC conversion circuitry. The switching DC—DC conversion circuitry provides the variable supply voltage based on an adjustable power control signal. By controlling the variable supply voltage provided to the one or more output stages, the switching DC—DC conversion circuitry controls an output power of the power amplifier based on the adjustable power control signal.
