I already had schematic in my Files area, now the PCB layout is available. Licensed under Creative Commons, feel free to use as you wish (don't forget to credit me and LZ1AQ).
I did some IMD measurements, results are similar to LZ1AQ design (on which it is based): +33..35dBm IP3 and +70..80dBm IP2.
The current is a bit lower for the similar IP3, because the first stage can be biased independently.
The 2nd stage can be used on its own as a 50 Ohm preamp with some component changes.
The input filtering may need more work to handle strong nearby broadcast stations better.
