General description
A 500 W LDMOS RF power transistor for broadcast transmitter applications and industrial applications. The transistor is optimized for digital applications and can deliver 110 W average DVB-T broadband over the full UHF band from 470 MHz to 860 MHz. The excellent ruggedness of this device makes it ideal for digital transmitter applications.
CAUTION
This device is sensitive to ElectroStatic Discharge (ESD). Therefore care should be taken during transport and handling.
