PTFA180701E
PTFA180701F
Thermally-Enhanced High Power RF LDMOS FETs
70 W, 1805 – 1880 MHz
Description
The PTFA180701E and PTFA180701F are 70-watt LDMOS FETs designed
for GSM and GSM EDGE power amplifier applications in the 1805 MHz to
1880 MHz band. Features include input and output matching, and thermally-
enhanced packages with slotted or earless flanges. Manufactured with
Infineon's advanced LDMOS process, these devices provide excellent
thermal performance and superior reliability.
