PTB 20081
150 Watts, 470–860 MHz
UHF TV Power Transistor
Description
The 20081 is a class AB, NPN, common emitter RF power transistor
intended for 28 to 32 Vdc operation across the 470 to 860 MHz UHF
TV frequency band. It is rated at 100 watts minimum output power.
Ion implantation, nitride surface passivation and gold metallization
are used to ensure excellent device reliability. 100% lot traceability is
standard.
