Shiny tiny board

A project log for Simple, low-cost FMCW radar

A basic radar system makes radar accessible at low cost for experiments with rangefinding & navigation of autonomous aircraft or spacecraft.

This is another little board quickly whipped up today... a basic, general-purpose breakout board or building block for a SOT-86 "Micro-X" MMIC amplifier. You could use this with essentially any one, from many different manufacturers such as Hittite, MiniCircuits, RFMD, or others - just tweak the resistor value and other components to suit the device and the frequency you are using. To allow easy access to the ground plane for hacking, I'm going to try fabricating this with no soldermask or silkscreen at all, and well, mainly just to see what the product looks like - in practice with these components the soldermask won't be needed for viable component placement and soldering, and the end result should be very metallic and shiny.
