175 Watts, 470–806 MHz
Digital Television Power Transistor
Description
The 20190 is a class AB, NPN, common emitter RF power transistor
intended for 28 Vdc operation across the 470 to 806 MHz UHF TV
frequency band. Rated at 175 watts output power, it is specifically
intended to operate uncorrected at 125 watts P-Sync (tested to EIA
Standard 4.1.3, Section 5, Method B for class AB transmitters at 125
watts P-sync) or at a minimum of 175 watts in PEP applications. It
may also be operated at comparable power levels for ATV broad-
casting. Ion implantation, nitride surface passivation and gold metalli-
zation ensure excellent device reliability. 100% lot traceability is
standard.
