FEATURES
DESCRIPTION
• Internal input matching to achieve high power gain
NPN silicon planar epitaxial transistor in an SOT-171
envelope, intended for common emitter, class-AB
operation in radio transmitters for the 960 MHz
communications band. The transistor has a 6-lead flange
envelope, with a ceramic cap. All leads are isolated from
the flange.
• Implanted ballasting resistors an for optimum
temperature profile
• Gold metallization ensures excellent reliability
QUICK REFERENCE DATA

Ruggedness in class-AB operation
The BLV98CE is capable of withstanding a load mismatch
corresponding to VSWR = 50 through all phases, under
the following conditions: VCE = 24 V, IC(ZS) = 30 mA,
f = 960 MHz at rated output power.

The circuit and components are located on one side of the PTFE fibre-glass board, the other
side being fully metallized, to serve as an earth. Earth connections are made by fixing screws,
hollow rivets and copper straps around the board and under the emitters, to provide a direct
contact between the component side and the ground plane.
