PTAC260302SC
Thermally-Enhanced High Power RF LDMOS FET
30 W, 28 V, 2620 – 2690 MHz
Description
The PTAC260302SC is a 30-watt LDMOS FET intended for use in
multi-standard cellular power amplifier applications in the 2620 to 2690
MHz frequency band. This device integrates a 10-W (main) and a
20-W (peak) transistor, making it ideal for asymmetric Doherty amplifier
designs. Features include input matching, high gain and thermally-
enhanced package with earless flange. Manufactured with Infineon's
advanced LDMOS process, this device provides excellent thermal
performance and superior reliability.
