Hi all, I m new to the group and wondering how deep and helpful discussions are. I m a PhD student trying to assemble Macom (MA4E1338A)diodes on a flexible FR9151 patterned substrate. Can I use any conductive epoxy (SPI Inc) for a frequency of operation of 915MHz. I could not see the rectified signal what so ever even when I manually soldered it to the substrate. All I see is a CW sinusoidal wave. Can anybody tell me where the problem is? Thank you,
