No, Sat, C25 has PF08103AA and 8210 has PF08103B
Hitachi marks "A" power amplifiers with 5v supply and "B" with 3v supply.
Power amplifiers can work, but with problems

I changed a week ago. And there was no problems at all. emitting strength was perfect. How is that possible?

Why PF08105 wont work on 8210? I solder in my phone this PA, and it is work in 900Mhz network, in mi opinion its all ok, but in 1800Mhz network does not work. But the phone is swith off some times, i dont know what the reason is.

Why did try to change PA08103 on PA08105 in 8210?
