In my chart recorders the modulating and demodulating was performed by the 50 Hz reed switch, and the germanium transistor AC amplifier was able to do a good job of working with the resulting 50 ...

Power Amplifiers for Research Applications Amp-Line Corp. provides a wide variety of wideband AC power amplifiers and power sources solutions for today 's industrial, commercial, military and ...

The essential conditions for a bipolar junction transistor to work as power amplifier ... There are wide varieties of amplifier depending on the requirement of • ac or dc amplification, • voltage, ...

The first transistor was about half an inch high ... This contraption was the very first semiconductor amplifier, because when a bit of current came through one of the gold contacts, another ...

Rufus Turner published plans for a crystal radio with a three-transistor audio amplifier back in 1950. Germanium transistors still find use in certain applications where their low forward voltage ...

In this chapter we will study the transistor differential-amplifier circuit. This is a very important transistor circuit, as it is the basis of the operational amplifier (or op amp), one of the most ...

In order to develop the necessary technology, the project Magellan—High Efficiency mm-Wave GaN Transistor High Power ...
