BLV58

DISCRETE SEMICONDUCTORS DATA SHEET BLV58 UHF linear push-pull power transistor Product specification September 1991 Philips Semiconductors Product specification UHF linear push-pull power transistor FEATURES High power gain Double stage internal input matching for high input impedance Diffused emitter-ballasting resistors enhances ruggedness Gold metallization for high reliability. DESCRIPTION The BLV58 is a common emitter epitaxial npn silicon planar transistor designed for high linearity class-A operation in UHF (bands 4 and 5) TV transmitters and transposers. The device is incorporated in a push-pull SOT289 flange envelope with a ceramic cap, which is utilized with the emitters connected to the flange.
