Rick, I just got the multiplier. It draws about 220mA at 15V, but won't produce any output. I've given it a wide range of input powers from very low up to about 20dBm. I took off the bottom cover, but it only exposes the back of a very complex circuit board. The only accessible parts are the trimmer caps which come through the PCB. Any suggestions?
