This is the circuit diagram of 2000W class AB power amplifier uses 7 pairs MJ15003 and MJ15004 transistors for the final amplification block. The circuit operated with 90V DC symmetrical (dual polarity) power supply circuit. The transistors must be mounted on heatsink to prevent the overheating...
Circuit diagram of the Doherty PA. Sign in to download full-size image Figure 6.5. Equivalent circuit model of the Doherty PA. As shown in Ref. [4], the transistor outputs are modeled as current sources controlled by their input voltages; thus, the output voltages of the main amplifier ...
Figure 4.12 is a circuit diagram of a practical 20 watt Class-A beam-tetrode amplifier. This amplifier utilises a balanced (or push-pull) output stage employing two 6L6 beam tetrode valves. This is the most common form of audio amplifier configuration. Why? The answer is balance. As with...
