    Summary form only given, as follows. A transistor oscillator with good amplitude and frequency stability and a low second-harmonic output is desirable to supply the excitation power for a second-harmonic-type magnetic modulator.

    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (54 KB)  

    Summary form only given. The maximum frequency at which a transistor can oscillate is a figure from which much of the high-frequency performance of the transistor can be predicted. For transistors of any given type, this measurement can be made easily in a circuit in which the tunedcircuit frequency and the feedback are the only two adjustable elements. The maximum frequency is in itself a useful ... View full abstract»

    Save to Project icon | Request Permissions | Click to expandAbstract | PDF file iconPDF (37 KB)  

    Summary form only given, as follows. Due to the dependence of transistor small-signal parameters on the d-c operating point (emitter current Ie and collector voltage Ve), the gain of a transistor amplifier stage decreases with either decreasing emitter current or decreasing collector voltage. Thus, we have two principles of gain control: Ie-control and V... View full abstract»
