Hi all,
I`m interested in Slovak microwave ham-radio and require help. Can me anyone help with constructing a simply microwave downconverter 2.1 - 2.3 Ghz to approx. 500-700 Mhz or help me with design of microstrip bandpass filters for these freqencies ?
The idea is build a low-cost downconverter with a non-profi parameters on a classic fibre-glass FR4 PCB material.
Thanks
Peter Rybar
