I already had asked this question around year ago, but still did not find out.

Actually it is the only important difference between this DRO and "classical" DROs. I mean that "right angle" part. Drain stub is half wavelength. Gate is terminated with 50 ohm. Angle between drain and gate lines must be 90 degrees, and somehow it have some advantage of "is not influenced in its oscillating characteristics by deviations of the transmission lines in size".
So why using right angle?
