DESCRIPTION N-P-N silicon planar epitaxial transistor intended for use in class-A, B and C operated mobile, industrial and military transmitters with a nominal supply voltage of 12,5 V. The transistor is resistance stabilized and is guaranteed to withstand severe load mismatch conditions with a supply over-voltage to 16,5 V. Matched hFE groups are available on request. It has a 3/8" capstan envelope with a ceramic cap. All leads are isolated from the stud.

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.

Conditions for R.F. SOAR f = 175 MHz Th = 70 C Rth mb-h = 0,45 K/W VCCnom = 12,5 V or 13,5 V PS = PSnom at VCCnom and VSWR = 1 measured in circuit of Fig.7. 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. The graph applies to the situation in which the drive (PS/PSnom) increases linearly with supply over-voltage ratio.
