Transistor Power Amplifiers Unit 1 – Circuit Board Familiarization
Exercise 1 – Circuit Location and Identification
EXERCISE OBJECTIVE
When you have completed this exercise, you will be familiar with the circuit blocks on the
TRANSISTOR POWER AMPLIFIERS circuit board. You will verify your results by identifying
circuit components and connecting two power amplifier circuits.
DISCUSSION
- Several types of transistor power amplifier circuits can be demonstrated with the
TRANSISTOR POWER AMPLIFIERS circuit board. - Fixed (15.0 Vdc) and variable positive dc positive supplies are used in the transistor
amplifier circuits. - Use the ATTENUATOR when small ac input signals are required.
- The DARLINGTON PAIR circuit block does not use a signal generator.
- The PHASE SPLITTER circuit block has two output signals.
- Transformers are used in input and output circuits of some power amplifiers.
