An amplification circuit and scaling method are configured to apply optimum biasing characteristics such that a multistage power amplifier operates according to defined performance characteristics. The operating conditions of the multistage amplifier are optimized by applying independent bias voltages to each stage within the multistage amplifier while operating in a maximum power output range. To achieve optimum or near-optimum operating conditions, each bias voltage is independently scaled acc...

A power amplifier circuit for peak envelope modulation of a high frequency signal is provided. The power amplifier circuit includes a transformer which receives a first signal greater than a predetermined level of an envelope of a carrier signal to generate a transformed signal, and a transistor which operates based on the transformed signal, receives a second signal, which is generated based on the carrier signal and has a direct current component, and amplifies the second signal according to t...

A method, or corresponding apparatus, assumes a call is a Voice Band Data (VBD) call. The method disables a local echo canceller and transmits a tone that disables distal echo canceller(s) along a communications path across which the call is communicated. After disabling the echo cancellers, the echo cancellers are allowed to operate in a typical manner, such as according to ITU standards, after the call is established, including remaining disabled if the call is a Voice Band Data call and being...

A portable multi-axis load confirmation tool having a rotating ball on the end thereof follows a three-dimensional weld program path therewith. The ball reacts to an internal load cell for verifying weld program path dynamics before an actual program is run with friction stir welding tools. The load cell is connected to instrumentation electronics converting a load cell signal to a digital readout and comparing the load cell signal to weld program load requirements. The tool integrates into a to...
