The BLF888E from Ampleon is an RF power transistor designed for DVB-T UHF asymmetrical wideband Doherty amplifier applications. This LDMOS transistor provides 150 watts of power with an effeciency over 50%, making this one of the highest power levels available from a single transistor for such broadcast applications. It provides a 120 MHz bandwidth per sub-band compared to the industry norm of 40 &ndash 50 MHz narrow bands for similar applications. The BLF888E has a 1:1.5 main/peak power ratio and are driven from a 50 VDC supply. It is available in a SOT539 package.
