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 amplifier applications in the 2300 to 2400 MHz frequency band.

Features include dual-path design, input matching, high gain and

thermally-enhanced package with earless flanges. Manufactured with

Wolfspeed's advanced LDMOS process, this device provides excellent

thermal performance and superior reliability.
