Diy Rf Signal Generator

In this video i show how the rf generator works and i go through some.

Diy rf signal generator.

I built my own rf signal generator by following plans from a nuts and volts magazine. It started when i read an article in the june 2014 issue of nuts and volts magazine. Rf generator with oscilloscope. Once our interest in electronics is piqued our inventory starts to grow first in knowledge gained by books and select articles followed by a small inventory of parts and a few pieces of basic test equipment.

Rf generator the frequency range of the generator can cover the whole hf spectrum depending on the value of the inductors and the variable capacitor. Following my build of a low cost vector network analyser last year i had a desire to add to my rf lab and with the parts i had remaining a simple rf signal generator seemed to be the obvious choice. Introduction this circuit came out of some work i did for the two antenna analysers which are described elsewhere on this site. Very useful feature of the rf signal generator is its modulation capability.

A full write up is included as a downloadable pdf file. If it can modulate the frequency amplitude or frequency makes it non replaceable tool for rf design works. This was not one of those projects. Diy rf signal generator.

Those instruments both include an rf signal generator. It has also a built in am modulator with an internal audio generator providing about 800hz tone or you can plug in an external audio signal to test and repair radio receivers. By robert reed view in digital edition skip to the extras. The rf signal generator is a must to have tool when playing with radio receivers.

The version i built was to fill in the gaps not covered by my old commercial unit and also provide an item of test equipment in its own right. The end result is shown above and is capable of sweeping between 23 5 mhz and 6ghz with 35 to 15 dbm of output power 25 to 10 guaranteed. The main category is rf sweep generatos projects that is about projects for rf sweep generators. Seemed like a great idea rather than spend a hundred fifty bucks on an rf signal generator for aligning my radios.

Some projects are easy. This is used as the signal source to drive the impedance bridge and detectors used to. It is used to tune a resonant circuits and adjust the gain of different rf stages. Hi welcome to my design for a simple and cheap rf signal generator with both am and fm modulation.

A 150 mhz rf signal generator for your test bench.
