Description

PTB 20176

5 Watts, 1.78–1.92 GHz

RF Power Transistor

The 20176 is a common emitter RF power transistor intended for 26
Vdc operation from 1.78 to 1.92 GHz. Rated at 5 watts minimum
output power, it is specifically designed for class A or AB linear power
amplifier applications. Ion implantation, nitride surface passivation
and gold metallization are used to ensure excellent device reliability.
100% lot traceability is standard.
