TDA2030 8 Watt Amplifier

TDA2030 8 Watt Amplifier

Although the TDA2030 can deliver 20 watts of output power, I deliberately reduced the output power to about 8 watts to supply 10 watt speakers. Input sensitivity is 200mV. Higher input levels naturally will give greater output, but no distortion should be heard.

The 500W Radio Power Amplifier

The 500W Radio Power Amplifier

For 160, 80 and 40 meter bands. With 58N20s it will deliver 400W on 40 and 700 on 160/80 meter band. The amp needs 25/35W of drive for full output.

The Audio / Video Distribution Amplifier

The Audio / Video Distribution Amplifier

With the amount of equipment in home entertainment centers today the need to be able to vary the gain of the audio or video signal is needed. It can give 3 outputs from one input

The Quest for the Ideal RF Amplifier

The Quest for the Ideal RF Amplifier

The basic function of a power amplifier is always the same: to boost a low-power signal to a higher power level, to be delivered to the amplifier load.

Variable Amplifier Impedance

Variable Amplifier Impedance

Is this a project or an article? Since you may have arrived here from either index, you might be a little confused. This is fine, as it has elements of both, but lacks the in-depth analysis of other articles, and also lacks the application of a final design that is common to my projects.
