Thermally-Enhanced High Power RF LDMOS FETs
180 W, 2110 â 2170 MHz
Description
The PTFB211803EL and PTFB211803FL are 180-watt LDMOS FETs
intended for use in multi-standard cellular power amplifier applications
in the 2110 to 2170 MHz frequency band. Features include input and
output matching, high gain and thermally-enhanced packages with
slotted or earless flanges. Manufactured with Infineon's advanced
LDMOS process, these devices provide excellent thermal perform-
ance and superior reliability.
