Today, February 20th, we have received a small batch of Angelia SDR board and the 10MHz buffer/switching module (small pcb on the lower right corner)
It’s an 8 layer board full of BGA’s, QFN, QFP, exotic and expensive components. More info on the Apache Labs web site https://apache-labs.com/al-products/1031/Angelia-Assembled–Tested.html
At first glance, it is obvious that the board we received is different from the commercial version shown on the Angelia page.
The board itself is smaller than I thought, with an impressive density of devices. 6 boards, 6 happy hams, and a long and complex project. We’ll have to assemble the rig from component level (and make it run), design a new version of the Alexiares filter board, choose and build a medium to high power SSPA with all the “bells and whistle” you can imagine (protection and control for VSWR, overvoltage, overcurrent, input power limitation, power supply filtering, “pure signal” coupler etc)
the first phase will probably takes one year
