This thin layer microwave absorber can be from 5mm up to 100mm thick.
The wavelength in microwave is relatively short: from 300mm long @1GHz through to 7.5mm long at 40GHz.
The thicker products are to address the 1-3GHz (300mm~100mm wavelength) range whereas above 10GHz (< 30mm wavelength) the absorbers can be thin.
The effect of installing absorber in a resonant cavity can have good effect beyond what would be expected compared to return loss figures.
