Hi all,

I've tried Googling, but Advanced Semiconductor have screwed the
search up with their worthless crap. What are the basic
characteristics of this device? Po, Ft, Gain, Vsupply, typical
application etc.

Thanks,

paul

It's a UHF NPN power transistor. At 400 MHz, with VCC=28 V, and PO= 10W,
the gain is 8.2 db (min). Maximum collector current is 1.25 amp, and max
dissipation is 20 W @ 25C derated .114 W/C. Claimed collector efficiency
is 60%. Moto must have second sourced this; it is in their 1991 RF book.

Yes, the "PT" was second sourced from TRW.
