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.
