Questions
How big is the K9HZ 100W 11band LPF Control PCB?
It measures 100 × 100 mm and has 4 copper layers, 1.65 mm thick.
What parts does the K9HZ 100W 11band LPF Control use?
155 parts, built around the AD8307AN, AD7991YRJZ-0RL, TC4428COA and SN74LVC1G04DCK. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the K9HZ 100W 11band LPF Control KiCad files?
From the DRWJSCHMIDT/K9HZ repository on GitHub, at the commit this page was made from: the board is K9HZ_LPF_Module/K9HZ_LPF_Schematics/K9HZ_100W_11band_LPF-Control/K9HZ_100W_11band_LPF-Control.kicad_pcb and its schematic K9HZ_100W_PA_MRF454_Vers/K9HZ_100W_PA_KiCad/K9HZ_100W_KiCad/K9HZ_100W_KiCad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the K9HZ 100W 11band LPF Control design in my own project?
Its repository states no licence, so its author keeps all rights: ask DRWJSCHMIDT before reusing the design.
