500 Watt Antenna Tuner Part 9 - Pre Build Schematics and Board Layout

 I am getting ready to order parts and build the tuner.  To prepare for it, I have updated the blog.  

I am planning to package the tuner on an open breadboard to showcase its construction.  It will be composed of three components (like the early prototype picture that I included in the matching algorithm page).  The three components are the directional coupler, the tuner controller and the RF deck.  

Here are the pages of the tuner controller:

Main/Microcontroller Page

Attenuator/Measurement Page

Controller Board Layout

And here are the pages for the RF Deck:

Main/Interconnect Page

Frequency Measurement Page

RF Path Page

RF Path Board Layout

Next, buy some parts, pay the prevailing tariffs, taxes and transportation, built and test.
