Inventory. In this chapter, we shall confine our attention to single stage transistor amplifiers. C. Multiplication of PMAX by the drain voltage and current ratings of a real device produces the maximum output power available from that device. 1 General Concepts: A power amplifier is one that is designed to deliver a large amount of power to a load. This article is solely dedicated to publish more transistor amplifier circuits. Second, does not connect the power transistors Q8, Q9 Amplifier Circuits Introduction to Impedance and Bandwidth Control. 3. Page: 3 Pages. 20W output. Application High power audio amplifier; Feature PDF Format. it use to give a very good quality of sound, eventhough it was a AC coupled amplifier. Power Commercially available audio amplifiers provide an output power of up to thousands of watts from very low power input. The function of a practical power amplifier is to amplify a weak signal until sufficient power is achieved to operate a loudspeaker or output device. com and is available currently as of the time this article is being MJ15004 Datasheet (PDF) - Motorola, Inc: Part # MJ15004: Download MJ15004 Download: File Size 119.
