PTF 10149
70 Watts, 921–960 MHz
GOLDMOS Field Effect Transistor
Description
The PTF 10149 is an internally matched 70–watt GOLDMOS FET
intended for cellular and GSM amplifier applications from 921 to
960 MHz. It operates with 50% efficiency and 16 dB typical gain.
Nitride surface passivation and full gold metallization ensure excellent device lifetime and reliability.
