Hello,
Looking for a datasheet for a Ma-Com SW-927 GaAs RF switch. No hits at all
from the usual suspects. Working on a HP 8990A peak power analyzer that's
loaded with them, and it appears that ALL their inputs (pin 1) are shorted
to pin 2 (GND)
(scratching head)
See https://home.comcast.net/~spam_gobbler/8990A.jpg
for the partial schematic if that helps. The point in question is U35 pin
1 which is the RF input from the front panel. All the switches after that
appear shorted as well on *both* baseband boards.
Thanks!
