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 broadcasting. Ion implantation, nitride surface passivation and gold metallization ensure excellent device reliability. 100% lot traceability is standard.
