Help identifying RF IC markings
I am trying to locate a manufacturer and part number for three RF parts in
some existing equipment (no docs available). The marking don't match anything I can find from the usual suspects, and no one's marking schemes seem similar. I'd appreciate if anyone can point me to the vendor. The first is a GaAs SPDT RF switch in a 6 pin SOT, and is marked "31E". Its pinout appears to be: 1 RF#1 2 Ground 3 RF#2 4 Control 5 RF Common 6 Ground The other two are amplifiers, labeled "4CH" and "4CJ". They are also in 6 pin SOT package with pinouts of 1 Ground 2 Ground 3 RF In 4 DC in 5 n/c 6 RF out Thanks, Steve |

Mini-circuits comes to mind but there does not seem to be a match.

Thanks, but its not a minicircuits part. They don't have a SOT package at
all. Steve "oppie" wrote in message news:GW8Qi.2681$I22.2011@trndny03... Mini-circuits comes to mind but there does not seem to be a match. http://www.minicircuits.com/ "Steve" wrote in message . ..
