README
README.mdAlexiares dual BPF for Orion/Anvelina SDR Board
1 to 60 MHz Band pass filter for dual ADC SDR (Orion class, Anvelina, Red Pitaya)
This pcb serves as RX bandpass for the new generation of Alexiares frontend
It replace the former Alexiares HPF filter and uses the very same SPI bus protocol
Please note that on BPF1
K23, FB45, FB46, R11, R12, C106 and C93 should NOT be soldered
(pads 3-10 and 9-4 should be strapped)
Signal RX2_GND is not used
BPF2 should be fully assembled, with K23, FB45, FB46, R11, R12, C106 and C93. Signal RX2_GND should be present on J6

Questions
How big is the Dual BPF PCB?
It measures 65 × 90 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Dual BPF use?
137 parts, built around the PGA-103, EC2-12NU and SS36. 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 Dual BPF KiCad files?
From the F6ITU/Dual_BPF repository on GitHub, at the commit this page was made from: the board is Dual_BPF.kicad_pcb and its schematic Dual_BPF.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dual BPF design in my own project?
Its repository states no licence, so its author keeps all rights: ask F6ITU before reusing the design.
