Simple LNB diode marker (harmonic multiplier)

Based on G3PHO marker generator.

Double LNB mixer diode can be used as well, but only one diode from the pair. Leave the third pin NC in the air.

Tested up to 24GHz, check the video, 1152MHz / 13dBm input = 10368MHz out

And the second one, 1336MHz / 13dBm input = 24048 MHz out (18th harmonic!!!)

If more signal required or wider range, place the diode across the Vivaldi type UWB antenna....
