Re: ATU-10: an alternative PCB layout?


 

Hello!

The BOM is also mostly the same as the , except that the TMMBAT41FILM detectors (diodes) are replaced with the AD8361 chips (SOT-23-5, 2 pcs).
Extra parts:
  1. 56,2 Ohm 1% resistor (1206), 2 pcs (to replace the original 50 Ohm ones)
  2. 287 Ohm 1% resistor (0603), 2 pcs
  3. 787 Ohm 1% resistor (0603), 2 pcs
  4. 1nF capacitor (0603), 2 pcs
  5. 10nF capacitor (0603), 2 pcs
  6. 1uF capacitor (0603), 2 pcs
  7. 10uF 16V tantalum capacitor (size A), 1 pcs
Also the pair of 47 kOhm resistors (0603, traces between the AD8361 outputs and the FWD, RFL test points) to be replaced with ~100 Ohm ones, or to be shorted alltogether.
There should be 10 turns in the "binocular" windings (instead of the original five turns).
Warm regards,
Tony
