PTAC240502FC
Thermally-Enhanced High Power RF LDMOS FET
50 W, 28 V, 2300 – 2400 MHz
Description
The PTAC240502FC is a 47-watt LDMOS FET with an
asymmetrical design intended for use in multi-standard cellular
power amplifi er applications in the 2300 to 2400 MHz frequency
band. Features include dual-path design, input matching, high gain
and thermally-enhanced package with earless fl anges. Manu-
factured with Infi neon's advanced LDMOS process, this device
provides excellent thermal performance and superior reliability.
