transistor primarily intended for use in
mobile radio transmitters in the
175 MHz commmunications band.
• multi-base structure and
emitter-ballasting resistors for an
optimum temperature profile
• gold metallization ensures
excellent reliability
• internal matching to achieve an
optimum wideband capability and
high power gain
The transistor has a 6-lead flange
envelope with a ceramic cap
(SOT-119). All leads are isolated from
the flange.

Fig.7 Printed circuit board and component lay-out for 175 MHz class-B test circuit.
The circuit and components are on one side of the epoxy fibre-glass board. The other side, except for the area indicated
by the dotted line, is unetched copper serving as a ground plane.
If the p.c.b. is in direct contact with the heatsink, the heatsink area within the dotted line has to be raised al least 0,5 mm
to minimize the dielectric losses.
Earth connections are made by hollow rivets and additionally by fixing screws and copper straps under the emitters to
provide a direct contact between the copper of the component side and the ground plane.

Ruggedness in class-B operation
The BLV75/12 is capable of withstanding a load mismatch
(VSWR = 20 through all phases) at rated load power up to
a supply voltage of 12,5 V; Th = 25 °C; Rth mb-h = 0,2 K/W.
Power slump
If Th is increased from 25 °C to 70 °C the output power
slump for constant PS amounts to typ. 7%
(VCE = 12,5; f = 175 MHz; Rth mb-h = 0,2 K/W).
