PTAC260302FC
Thermally-Enhanced High Power RF LDMOS FET
30 W, 28 V, 2620 – 2690 MHz
Description
The PTAC260302FC 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
Wolfspeed's advanced LDMOS process, this device provides excellent
thermal performance and superior reliability.
