Amplifier having digital bias control apparatus

摘要

This amplifier is equipped with a digital bias control apparatus to provide precise, dynamic control over the operating point of a plurality of amplifying elements in the ampliifer. A processor optimizes the operating point of each individual amplifying element as a function of the amplifying element characteristics, the operating environment and the applied input signal. The use of a processor also enables the user to remotely program the operating point of each individual amplifying element in the amplifier. The processor further enables dynamic changes in the operating characteristics of the amplifier as the operating environment of these amplifing elements changes. The processor also generates an alarm signal if any particular amplifying element is operating out of its nominal specifications. This digital bias control apparatus can function in class A, AB, B or C type of amplifiers whether they are tuned or untuned and whether the amplifier operates in a pulsed or continuous mode.
