The PKU100 from Rohde & Schwarz is a solid-state power amplifier for the Ku band (13.75 to 14.50 GHz) with a peak power of 400 W and peak efficiency of over 20%. This amplifier combines the advantages of solid-state and tube-based amplifiers. It features optional adaptive linearization at the RF level to provide a previously unattainable spectral purity. The linearization changes the input signal and optimally compensates the amplifier’s nonlinearities, significantly increasing the signal quality to the satellite, both inside and outside the wanted signal’s bandwidth.
The amplifier is available in a 3 HU rack mount unit and operates from 230 V AC supply, consuming less than 6.5 A of current. This device can also be operated from a 48 V DC supply.
