摘要：
Current feedback is used to adjust the quiescent emitter current of an r-f amplifier transistor to prescribed idling or stand-by value, to avoid undesirable quiescent base-input-impedance conditions, but is disabled upon application of r-f drive to the base electrode of the r-f transistor so that operation which is other than Class A is not interfered with.
