FM amplifier with output power or 1 kW is realized in MOSFET  technology, with two pair of balanced amplifiers. Signal dividing and combining in this amplifier is realized with Wilkinson dividers / combiners. 
The power gain is better than 19 dB  in whole band.  
The amplifier is situated in standard rack 19" wide and 5H high.
