RF power transistor has highest figure of merit

The MRF6VP3450H 50-V laterally diffused MOS (LDMOS) RF power transistor is offered as providing 50% higher output power than competing UHF TV broadcast solutions and demonstrates an industry-leading RF figure of merit. The transistor delivers greater than 450-W peak power at P1dB with 50% efficiency throughout the UHF broadcast frequency band.

Designed to offer a combination of power, efficiency, and gain for any RF power transistor, it targets the 470 to 860-MHz TV broadcast frequencies. It uses a DVB-T 64 QAM OFDM signal at 90-W average output power with a typical 860-MHz 50-V performance, 28% drain efficiency, and 23-dB gain, with an adjacent channel power ratio (ACPR) at 4-MHz offset of 62 dBc in a 4-kHz bandwidth. The transistor can help ease the transition from analog to digital TV broadcast. (Contact company for pricing — sampling available now; prod qty, 3rd qtr.)
