ceramic cap. All leads are isolated
from the stud.
DESCRIPTION

transistor intended for use in class-A,
B and C operated mobile, h.f. and
v.h.f. transmitters with a nominal
supply voltage of 13,5 V. The
transistor is resistance stabilized and
is guaranteed to withstand severe
load mismatch conditions with a
supply over-voltage 16,5 V.

Fig.8 Component layout and printed-circuit board for 175 MHz test circuit.
The circuit and the components are situated on one side of the epoxy fibre-glass board, the other side being fully
metallized to serve as earth. Earth connections are made by means of hollow rivets, whilst under the emitter leads Cu
straps are used for a direct contact between upper and lower sheets.

Note to Fig.11:
The transistor has been developed for use with
unstabilized supply voltages. As the output power and
drive power increase with the supply voltage, the nominal
output power must be derated in accordance with the
graph for safe operation at supply voltages other than the
nominal. The graph shows the permissible output power
under nominal conditions (VSWR = 1), as a function of the
expected supply over-voltage ratio with VSWR as
parameter.
