150 Watts, 470–860 MHz
UHF TV Power Transistor
Description
The 20237 is a class AB, NPN, common emitter UHF TV power
transistor intended for 28 Vdc operation from 470 to 860 MHz. Rated
at 150 watts minimum output power, it may be used for both CW and
PEP applications. Ion implantation, nitride surface passivation and gold
metallization ensure excellent device reliability. 100% lot traceability
is standard.
