I am building a family of low cost shield boards that will enable makers and hobbyists to dip their toes into the world of microwave circuits. With Arduino, Teensy and R Pi compatible shields, makers will finally be able to experiment with stuff they don't see in everyday electronics: frequency synthesizers, spectrum analyzers, RSSI detectors, IQ modulators, network analyzers and many more. High frequency circuits always seemed a bit like a black magic - I hope this project will encourage many to prove it isn't.
I will start with a simple frequency synthesizer, that is based on my previous project, Microwave transmitter. Synthesizer, based on Maxim Integrated chip MAX2871, will synthesize frequency in range 23.5 MHz - 6000 MHz. Neat, eh?

Today I finished project design and sent everything to fabrication. I ordered PCBs from OSH Park (5$) and kepton stencils from OSH Stencils (8.45$ with shipping). I expect to get everything ready for assembly in next 20 days. Till then, over and out!
