Confidential, Limited Internal Distribution
Thermally-Enhanced High Power RF LDMOS FET
240 W, 1450 – 1500 MHz
Description
The PTFA142401EL and PTFA142401FL are 240-watt LDMOS FETs
designed for DVB and DAB applications in the 1450 to 1500 MHz
frequency band. Features include internal I/O 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.
