The driver behind the project is Tim Tuck, VK2XAX, who run a very successful project where they crowdfunded via fundrazr.com for 350 units.   <\/p>\n\n\n\n<p>The original design was presented in DUBUS magazine, an international microwave experimenters publication, and the original project was developed by Andrew, VK3CV \/ WQ1S.  The design has already been used to break many Australian 122G distance records.

Here is a link to the TRA_120 component <a href=\"https:\/\/siliconradar.com\/products\/single-product\/120-ghz-transceiver-tra_120_002\/\">https:\/\/siliconradar.com\/products\/single-product\/120-ghz-transceiver-tra_120_002\/<\/a>.   The component is a 5mm x 5mm QFN32 package, which will be a small challenge to work with.  Fortunately, I have the Surface Mount gear to help make it a success.<\/p>\n\n\n\n<p>Next to do is the Mouser order for the rest of the components &#8211; The board is run with a ADF4153 PLL and a Microchip 16LF877, and the rest of the components is pretty standard fare, so its quite achievable.<\/p>\n\n\n\n<p>Watch this space &#8211; More to come as I progress the project \ud83d\ude42<\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>(The cover photo for the project is Andrews dish (VK3CV\/WQ1S) from the DUBUS article.)
