here ya go . all power ratings are PEP . it rated at 100 watts pep @ 28 MHz.
2SC2879 Datasheet pdf - TRANSISTOR SILICON NPN EPITAXIAL PLANAR TYPE 2~30MHz SSB LINEAR POWER AMPLIFIER APPLICATIONS (LOW SUPPLY VOLTAGE USE) - TOSHIBA
page 2 : input power , 6 watts typical 10 watts max
page 1 : maxium collector power dissipation 250 watts .
look at the graphs on page 3 for the power input to output ratios .
after 8 or 10 watts it starts leveling off , compression is setting in . can still do more watts though .
the intermodulated graph shows how distortion is related to input .
its at its lowest at 60 watts and starts rising from there .
does anyone think its get cleaner when you go beyond 100 watts ?
this is what Toshiba says . they designed and manufacture it .
i guess the folks claiming 200 , 300 and 400 watts out of them know something the folks at Toshiba doesnt .
i know power meters are broad banded devices and dont know what frequencys/harmonics are showing up as power on those meters .
