Compact Amplifier for Latest-Generation Satellite Uplinks
With its new R&S PKU100, Rohde & Schwarz is entering the market for satellite uplink amplifiers in the Ku band. The PKU100 combines the best of two worlds in a single device: the unbeatable strengths of solid-state amplifiers and the compactness and low weight of tube amplifiers. Adaptive linearization makes the PKU100 truly innovative.
The PKU100 ushers in a true technology shift in uplink signal amplification. The device uses solid-state output stages throughout and offers a genuine alternative to conventional tube technology. Should individual transistors fail, for example, the amplifier will continue to operate at reduced power.
The PKU100 is just as light, compact, and energy-efficient as conventional tube amplifiers and therefore clearly superior to comparable semiconductor-based products. No other instrument on the market offers adaptive linearization. This improves signal quality, enabling network operators to transmit significantly more data over the same signal bandwidth. The amplifier offers excellent efficiency, reducing operating costs.
The PKU100 is available in indoor and outdoor versions. It can be used in ground stations and satellite news gathering (SNG) vehicles.
Rohde & Schwarz has put a lot of thought into the amplifier’s power supply concept. If fitted with an optional redundant power supply, the PKU100 will continue to operate should one of the power supplies fail.
The solid-state amplifier comes in 400 W and 750 W versions, each with a frequency range from 12.75 GHz to 13.25 GHz and 13.75 GHz to 14.5 GHz, covering the Ku band. The PKU100 can be fitted with a block upconverter (BUC), allowing low-frequency L-band signals to be processed and converted to the Ku band. The amplifier can be controlled remotely; it supports all common standards such as a web interface, SNMP, RS-232, and parallel I/O interfaces.
The PKU100 will be available by June 2018.
