RFMW 750W LDMOS Transistor for Doherty Transmitters

The Ampleon BLF888E operates from 470 to 790 MHz serving broadcast applications with 150W average power.RFMW, Ltd. announces design and sales support for a UHF, power LDMOS transistor designed for asymmetrical Doherty transmitters. The Ampleon BLF888E operates from 470 to 790 MHz serving broadcast applications such as DVB-T (8k OFDM). The BLF888E provides 150 watts of average power in this application with up to 17dB of gain and 52% efficiency. Ampleon’s high efficiency helps reduce the end product’s energy consumption profile. The BLF888E provides a typical 120 MHz bandwidth per sub-band, almost 3X the industry norm for similar applications. Operating from a 50V supply, the BLF888E has integrated ESD protection aiding its excellent reliability. This Ampleon transistor is offered on a flange with two mounting holes or an earless flange, the BLF888ES.
