A simple logic probe in concert with a signal source can be used to check digital as well as linear circuits. With the flick of a switch, the probe can inject a test signal or check the logic state of a digital signal. Comprising just one CMOS IC (CD4011B) and a handful of components, the […]

A collection of fundamental electronic circuits designed for amateur radio and RF experimentation. Explore detailed schematics for VFOs, power amplifiers, band-pass filters, and voltage regulators. These resources provide the essential building blocks for homebrew projects, focusing on circuit stability, impedance matching, and practical bench-testing techniques
MAX2633 based VHF Preamplifier using for entire VHF band
Here is a high performance RF amplifier using MAX2633 for the entire VHF band that can be successfully built without any special test equipment. The grounded -gate configuration is inherently stable without any neutralisation if reasonably good layout techniques are employed. The performance of the amplifier is quite good. The noise figure is below 2dB […]
