In an earlier article, the author described a 50 MHz 125V 250W class C amplifier using the ARF448A/B high voltage MOSFET devices. This paper now describes an improved version of that amplifier which ...

This was a big and well-equipped e900 integrated amplifier with a tube voltage gain stage and MOSFET outputs. It was also one of the ... but if LFD do a reasonable job for the same money, and if Audio ...

Temperature variations can affect the performance and stability of a MOSFET amplifier, especially in the DC biasing circuit. The Q point, or quiescent point, is the operating point of the ...

It doubles the operating frequency of previous high efficiency amplifiers using MOSFET transistors in the TO-247 package. Device criteria, circuit design, and amplifier performance characteristics are ...
