DESCRIPTION
FEATURES
N-P-N silicon planar epitaxial transistor primarily intended
for use in mobile radio transmitters in the 900 MHz
communications band.
• multi-base structure and emitter-ballasting resistors for
an optimum temperature profile
• internal input matching to achieve an optimum wideband
capability and high power gain
• gold metallization ensures excellent reliability.
The transistor has a 6-lead flange envelope with a ceramic
cap (SOT-171). All leads are isolated from the flange.

The circuit and the components are on one side of the P.T.F.E. fibre-glass board; the
other side is unetched copper serving as ground plane. Earth connections are made by
fixing screws and copper straps around the board and under the emitters to provide a
direct contact between the copper on the component side and the ground plane.
