Thermally-Enhanced High Power RF LDMOS FETs
170 W, 725 – 770 MHz
Description
The PTFA071701E and PTFA071701F are 170-watt, LDMOS FETs
designed for use in cellular power amplifiers in the 725 to 770 MHz
frequency band. Features include internal I/O matching, and
thermally-enhanced, ceramic open-cavity packages. Manufactured
with Infineon's advanced LDMOS process, these devices provide
excellent thermal performance and superior reliability.
