The last board showed some power leak. The expected power could not be reached. It even degraded to 40mW - bad. Now I made a new board with better connectors and more careful routing which is ready for testing in Dresden.

It is prepared for the highly sensitive scale and can deliver more than 200mW with 24GHz at 85°C (after cable- and connector lossed), so we should not get thermal issues this time. The ALU-Plate will be also fixed to the scale for better heat dissipation.The cavity is new (blogged about it before). It shows two clean resonance peaks at which we will test for thrust.Sweeps will also be made in case there are some other phenomena which may occur beside the two resonance frequencies.For an eventual integration into a satellite, the board can find and track the resonance peaks automatically.

I´ll make a 360° video of the test preparation in Dresden (if allowed).
