Caractéristiques & avantages

Excellent power efficiency

Up to 50% cost savings for reduced power levels and 1+1 systems

The R&S®PKU100 reaches unparalleled efficiency in relevant use cases with reduced power levels and backup amplifiers that spend most of the time on standby. When operating at 100W (Plin), the 400W-model consumes just 950 W of mains power. Efficiency is equal to 10% (@Plin) reducing energy costs by 25% compared to typical TWTAs. And in 1+1 configurations, savings doubles thanks to extremely low backup amplifier power consumption.

**High efficient satellite earth stations** - Operating Ku-band links with R&S®PKU100 uplink amplifiers significantly saves costs

Adaptive linearization

Unparalleled spectral purity

This R&S®PKU100 is the only amplifier with adaptive linearization within the Ku-band frequency, essential for minimizing intermodulation products and optimizing power efficiency. No user interactions or adjustments required, since the linearizer adapts to provide the best possible signal performance. This feature significantly improves transmission quality, especially for higher order modulation schemes.

Smart operation

Simplifying work for ground station operators

Operating and maintaining an R&S®PKU100 is very easy. It offers a sophisticated graphical user interface with monitoring capabilities and comes with self-protection mechanisms to eliminate accidental harm. In the event of a failure, the R&S®PKU100 stays on air. Redundant power supplies and parallel signal paths eliminate single points of failures known from traveling wave tube amplifiers (TWTA).

Compact and lightweight

3U for 400W and 750W

The 400 W indoor model weighs just 18 kg (including power supply) and requires only 3 RU of rack space. Comparable solid-state amplifiers usually weigh twice as much. The R&S®PKU100 produces up to 750 W saturated output power and is one of the most compact solid-state power amplifiers (SSPA) on the market.

**R&S®PKU100-I for 19" rack integration** - The R&S®PKU100-I fits into 3 RU rack space and weighs 18 kg
