PTFA081501E
PTFA081501F
Thermally-Enhanced High Power RF LDMOS FETs
150 W, 864 – 900 MHz
Description
The PTFA081501E and PTFA081501F are thermally-enhanced,
150-watt, internally matched
GOLDMOS
®
FETs intended for ultra-
linear applications. They are characaterized for CDMA and
CDMA2000 operation from 864 to 900 MHz. Thermally-enhanced
packages provide the coolest operation available. Full gold
metallization ensures excellent device lifetime and reliability.
