PTFB182557SH
Confidential, Limited Internal Distribution
Thermally-Enhanced High Power RF LDMOS FET
250 W, 28 V, 1805 – 1880 MHz
Description
The PTFB182557SH is a 250-watt LDMOS FET specifically designed
for use in Doherty cellular power amplifier applications in the 1805
to 1880 MHz frequency band. Input and output matching has been
optimized for maximum performance as the peak side transistor in
Doherty amplifiers. Manufactured with Infineon's advanced LDMOS
process, this device provides excellent thermal performance and
superior reliability.
