Product specification

HF/VHF power transistor

BLW86

Ruggedness in s.s.b. operation

The BLW86 is capable of withstanding a load mismatch (VSWR = 50) under the following conditions: class-AB operation;

R.F. performance in s.s.b. class-A operation (linear power amplifier)

Note

1. Stated intermodulation distortion figures are referred to the according level of either of the equal amplified tones.

Relative to the according peak envelope powers these figures should be increased by 6 dB.
