15 Year Old Spectrum Digitizer Cards Still Playing A Vital Role at DESY

DESY, short for Deutsches Elektronen-Synchrotron, is based in Hamburg, Germany and operates particle accelerators to investigate the structure of matter. The accelerators run 24/7 for international experimenters so it is vital to have equipment that can be relied on to work perfectly and for many years. Spectrum Instrumentation has become one of DESY’s suppliers of choice for digitizer cards for the past fifteen years because of its reputation for quality.

New RadioVerse Transceivers Extend Cellular, Phased Array Radar and T&M Capabilities

Analog Devices (ADI) is expanding its RadioVerse™ transceiver family with three new products offering improved performance and features tailored for wireless infrastructure, phased array radar, military communications and test and measurement applications. The ADRV9008 is a two-chip transceiver (i.e., one each for transmit and receive) for frequency-division duplex (FDD) systems, and the ADRV9009 is a single chip transceiver for time-division duplex (TDD) systems.

Wideband Noise Parameter Measurements at Hot and Cryogenic Temperatures

For LNAs with exceptionally low noise temperatures — on the order of just 1 or 2 K — the measurement of noise performance is difficult and subject to systematic errors from noise source uncertainties. NoiseTech Microwave offers a line of solid-state impedance generators with cryogenic capabilities, supporting a cold noise parameter measurement approach. The impedance generator presents four signal source impedances at the input to the device under test, enabling noise parameters to be deterministically extracted.
