BLV194

Product Overview

BLV194 is a Philips / NXP UHF NPN RF power transistor designed for common-emitter class-AB operation in the 900MHz communications band. The device uses silicon planar epitaxial transistor technology and is built in a SOT171 flanged package with a ceramic cap for RF power amplifier applications. With emitter-ballasting resistors, gold metallization, UHF power capability and rugged RF package construction, it is suitable for 900MHz communication transmitters, RF driver stages, mobile radio equipment, telemetry systems, low-power base station amplifiers and RF equipment repair projects.
