Our partner: ELVA-1

ELVA-1 is a worldwide leading expert for millimeter- and submillimeter-wave related components, subsystems and solutions within the 26 GHz to 220 GHz frequency range. ELVA-1 offers the same product line for higher frequencies up to 1.200 GHz too.

The company focuses its research and development efforts towards millimeter- and submillimeter- wave technologies and produces components and devices with unique performance characteristics. Since the year 2000 ELVA-1 aggressively pushes its product range into mm-wave telecom products.

One of the company’s highlights is the DPM Power Meter series test equipment. The application of individual power sensors allows measuring signals in the frequency band from 0.01 GHz to 220 GHz.

The DPM Power Meters are mainly used for power calibration of the R&S®ZVA-Zxx millimeter wave converter series which extend the operating bandwidths of the R&S network analyzers to higher frequencies.

The ELVA-1 DPM power meter helps to get a flat and defined output power vs frequency of the R&S®ZVA-Zxx converters.

The DPM power meters can be used also for standard power level measurement applications.
