I recently aquired (second-hand) a Yaesu FT-252 handheld in unknown condition. It turned out to mostly work, but was found very weak. Investigating it in the HAM club we found that the PA IC is very likely to be at fault, as we could detect signals going into it, but no signals getting out at all. We also found that it's most likely to be shorted, as we measured \$<5\Omega\$ between one of it's (non-ground) pins and ground.
We tried to search for this part, but could not find any info on it. We tried to search for "W62Y106", "2Y106", "W6 2Y106" and most similar combinations with no success.
One of the members of the HAM club suggested that we might just replace it with some "generic" 5W RF PA suited for the 2m band.
a) What could be the part number of this IC (marked "W6 / 2Y106"), so we can find datasheet or order it?
b) What other RF PA ICs could be used as a replacement, that we can buy?
