Here we repair a KALMUS 710FC-CE 10 Watts RF power amplifier with a special 1GHz Bandwidth, comprising of four modules, we repair the unit to component level & use various instruments in the sweep & power measurements for adjusting the linearity across the 1GHz bandwidth. This is a very rare & expensive amp used in defence & aerospace lab grade with exceptional performance across 1MHz to 1GHz maintaining a linear output of 40db gain across the entire spectrum. In this repair we encounter a number of challenges with getting spare parts, & adjusting the amplifiers output amps & combiner which all have problems. Join me on this adventure as together we take the bull by the horns & tackle this difficult multi fault amplifier ending with a successful repair.

I would say power for each amp imput is 14dBm indeed as preamp 20dBm is split into 4, that is -6dB... So correct imput is 14dBm expected output is around 34dBm each
