Confidential, Limited Internal Distribution
Thermally-Enhanced High Power RF LDMOS FETs
90 W, 28 V, 920 – 960 MHz
Description
The PTFB090901EA and PTFB090901FA are 90-watt LDMOS
FETs intended for use in multi-standard cellular power amplifier
applications in the 920 to 960 MHz frequency band. Features in-
clude input and output matching, high gain and thermally-enhanced
packages. Manufactured with Infineon's advanced LDMOS pro-
cess, these devices provide excellent thermal performance and
superior reliability.
