PTFA191001F
Confidential, Limited Internal Distribution
Thermally-Enhanced High Power RF LDMOS FETs
100 W, 1930 – 1990 MHz
Description
The PTFA191001E and PTFA191001F are thermally-enhanced,
100-watt, internally-matched LDMOS FETs intended for WCDMA,
IS-95 and CDMA2000 applications. They are characterized for single-
and two-carrier WCDMA operation from 1930 to 1990 MHz.
Thermally-enhanced packaging provides the coolest operation
available.
