Abstract :
A power amplifier (hereinafter referred as PA) for a transmitter of the bandwidth (30...180) MHz with output power of 1 kilowatt is designed. The amplifier is able to operate into load with KWR of 2,5. A power division bridge and a power addition bridge, a directional coupler, harmonic filter and 1 kilowatt artificial load-attenuator with VSWR les 1.2 were developed for the transmitter.
