UHF linear push-pull power transistor
BLV58
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.
