APPLICATION INFORMATION
R.F. performance in u.h.f. class-AB operation (c.w.)
Note
1.
Typical values are based on 1 dB gain compression. Using a 3rd order amplitude transfer characteristic, 1 dB
compression corresponds with 30% sync input/25% sync output compression in television service (negative
modulation, C.C.I.R. system).
