摘要： A first transistor stage has a tuned output circuit. A coil coupled to the tuned output circuit has, in parallel with it, a series circuit of a resistance and a pair of diodes connected in parallel but with opposite polarity. Terminal of the resistance not connected to the pair of diodes may be connected to the top of the coupling coil via a resistance and is connected to the base of the subsequent transistor stage.
