Rohde & Schwarz has unveiled a satellite uplink amplifier in the Ku band., that combines the unbeatable strengths of solid-state amplifiers and the compactness and low weight of tube amplifiers. The R&S PKU100 is available in indoor and outdoor versions. It can be used in ground stations and satellite news gathering (SNG) vehicles.
The R&S PKU100 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.
R&S asserts that the new product is just as light, compact and energy-efficient as conventional tube amplifiers and therefore clearly superior to comparable semiconductor-based products.
The amplifier is also said to be the first to offer 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.
In addition, the amplifier can be fitted with an optional redundant power supply, allowing continued operation 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 R&S 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 R&S PKU100 will be available from Rohde & Schwarz as of June 2018.
