Questions
How big is the RF Amplifier PCB?
It measures 70 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RF Amplifier use?
30 parts, built around the MMZ09332BT1 and AMS1117-5.0. 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 RF Amplifier KiCad files?
From the Eugene91/pcb_training repository on GitHub, at the commit this page was made from: the board is RF_Amplifier_1W/RF_Amplifier/RF_Amplifier.kicad_pcb and its schematic Heater wirebonding/Heater wirebonding.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the RF Amplifier design in my own project?
Its repository states no licence, so its author keeps all rights: ask Eugene91 before reusing the design.
