250mW Power Amplifier Kit

SKU: QK171
This project is a simple 2-transistor VHF power amplifier, with about 16dB gain, and requires no tuning or alignment procedures. Wideband techniques have been used in the design and the circuit is equipped with a "low-pass" filter to ensure good output spectral purity.

Availability: In stock
Assembly Required: Yes

Product Description


    The project has been designed for assembly on a single-sided printed circuit board. The circuit is specifically designed to amplify the output of 7mW to 10mW WBFM transmitters (wide band) to a final level of 250mW to 300mW, after the filter. This amplifier is an excellent companion to the low-power FM microphones in the 7mW to 10mW range. In addition to exercising basic soldering skills, it also introduces the builder to some simple RF tests and basic techniques for higher power projects. When you assembled the amplifier, you learned, or exercised, basic soldering skills. Testing the amplifier required some basic RF amplifier tests. These most basic tests should always be done when checking out any RF amplifier.
