... of noise in high-Q LC and crystal oscillators which are widely used in high-frequency receivers. Noise in these circuits is filtered into a narrow bandwidth by the high-Q frequency-selective elements. This fact allows a relatively simple analysis of the noise in the oscillation, the results of which ...

... When R1 is connected to the collector, the transistor has to “work” to get the output voltage close to zero. However, this circuit has the advantage that no signal inversion occurs. In bench tests it was possible to bridge more than 2” with the circuit from Figure 1, when the IR diode was driven wit ...

Valve RF amplifier



A valve RF amplifier (UK and Aus.) or tube amplifier (U.S.), is a device for electrically amplifying the power of an electrical radio frequency signal.Low to medium power valve amplifiers for frequencies below the microwaves were largely replaced by solid state amplifiers during the 1960s and 1970s, initially for receivers and low power stages of transmitters, transmitter output stages switching to transistors somewhat later. Specially constructed valves are still in use for very high power transmitters, although rarely in new designs.
