Rohde and Schwarz to Present Compact Amplifier for Satellite Uplinks

The R+S PKU100 from Rohde and Schwarz 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 R+S 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 linearisation. 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 R+S PKU100 is available in indoor and outdoor versions. It can be used in ground stations and satellite news gathering (SNG) vehicles.

Rohde and Schwarz has put a lot of thought into the amplifier’s power supply concept. If fitted with an optional redundant power supply, the R+S PKU100 will continue to operate should one of the power supplies fail.

The solid-state amplifier comes in 400W and 750W versions, each with a frequency range from 12.75GHz to 13.25GHz and 13.75GHz to 14.5GHz, 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 and Schwarz as of June 2018. It will be presented at the Satellite Show in Washington at booth 2216.
