Overview
e PTB 20174 90 Watts, 1400–1600 MHz RF Power Transistor Description The 20174 is an NPN, common emitter RF power transistor intended for 26 Vdc class AB operation from 1400 to 1600 MHz.
Rated at 90 watts minimum output power, it may be used for both CW and PEP applications.
Ion implantation, nitride surface passivation and gold metallization are used to ensure excellent device reliability.
100% lot traceability is standard.
