It includes a set of software that is extremely useful and is referenced to in the book. Wes Hayward (W7ZOI)’s software package that comes with the book Experimental Methods in RF Design (EMRFD) is called LADPAC. :( I consider the L/C meter kit he use to sell to be one of the greatest investments I made as a homebrewer,įor intermediate frequency crystal ladder filters I use Dishal Crystal Ladder Filter Program. The Elsie software by Tonnesoft is alright too but I generally prefer AADE’s filter design program. Most of them are very well known already but I will include them here in hopes that someone may find it useful:įor RF LC Filters (like a BPF for a receiver or LPF for a transmitter) I usually use: AADE Filter Design.

I would like to share the names of some of the software I use for radio frequency design. LTSpice is excellent too but QUCS is a great resource for RF circuit simulation. It can be difficult to learn but there are some great video tutorials to help. I enjoy using QUCS, as a homebrewer / wannabe / hobbyist RF circuit experimenter. Posted in Software Hacks Tagged circuit, psim, PSpice, qucs, simulation, software, SPICE Post navigation If you’re new to the world of circuit simulation, we went over the basics of using SPICE in a recent Hack Chat. For more details, the Qucs Wikipedia page lists all of the features available, as does the project’s FAQ page. Qucs has most of the components that you’ll need for professional-level circuit simulation as well as many different transistor models. Qucs runs its own software separate from SPICE since SPICE isn’t licensed for reuse. Luckily, there’s a fully featured free and open source circuit simulation software called Qucs (Quite Universal Circuit Simulator), released under the GPL, that offers a decent alternative to other paid circuit simulators.

While it’s easy to get a trial version of something like OrCAD PSpice, this software doesn’t have all of the features available unless you’re willing to pony up some cash.

But if you have a more complicated circuit, or if you need to do response modeling or other math on your design before you start building, you’ll need circuit simulation software. Breadboards make it easy to check your circuit for mistakes before soldering together a finished product. For simple circuits, it’s easy enough to grab a breadboard and start putting it together.
