ERZIA Contributes to Breakthrough QV-LIFT Program

2020 was a remarkable year for innovation in the satellite communications arena. The QV-LIFT program was completed, bringing great promise for the future. QV-LIFT is an EU-sponsored Horizon2020 Research and Innovation Action committed to increasing the maturity level of key satellite communication technologies and to contributing to a more competitive positioning of SatCom European manufacturers in the marketplace.

ERZIA RF AMPLIFIERS ENABLING CHANG’E-5 MOON EXPLORATION

Could the moon be billions of years younger than we thought? Samples collected during China’s Chang’e-5 mission enabled in part by ERZIA will tell us soon. ERZIA has long designed, developed, and manufactured space qualified RF and microwave devices for the space/aerospace industry. This year ERZIA amplifiers are instrumental in a breakthrough mission with China’s Chang’e-5 moon lander probe, which will collect the youngest lunar samples ever and deliver them to Earth via a lunar orbiter around December 16, 2020. The lander was launched on November 23, 2020.

ERZIA Celebrates Contribution to Mission Success

ERZIA congratulates Stefano Vitale, this year’s recipient of the Tycho Brahe Medal. The medal recognizes his leadership of the Laser Interferometer Space Antenna (LISA) Pathfinder mission. The award, bestowed by The European Astronomical Society, acknowledges the mission’s extraordinary success proving the technology required for the gravitational wave observatory planned to be launched in 2034.

Wideband HPA (WHPA) Delivers 37 dBm Consistently from S- through K-band

ERZIA Technologies, an RF/microwave amplifier and integrated assembly company delivering COTS solutions for high-performance/high frequency applications, has announced the release of a new, compact, Wideband High Power Amplifier (WHPA) that operates from 2 to 20 GHz ( S-band through K-band) while providing 37 dBm of output power and 36 dB of gain.

Innovatively Powered AOTFs Help a Spectrometer Transmit Eye-opening Data from Mars

Spectrometers employing acousto-optic tunable filters (AOTFs) are rapidly gaining popularity in space, and in particular on interplanetary missions. According to a paper published by the National Center for Biotechnology Information, “they allow for reducing volume, mass, and complexity of the instrumentation and are used for analyzing ocean color, greenhouse gases, atmospheres of Mars and Venus, and for lunar mineralogy. The AOTFs are used in point (pencil-beam) spectrometers for selecting echelle diffraction orders, or in hyper-spectral imagers and microscopes.”

The NOMAD instrument, with ERZIA amplifiers on board, makes a great discovery in Mars’ atmosphere.

In 2014, ERZIA delivered RF Driver Amplifiers for the NOMAD instrument for installation on the Trace Gas Orbiter (TGO) of the ExoMars mission. The mission was launched in 2016 and NOMAD began science operations in 2018.

How to Design RF Amplifiers for Space-based Acousto-optic Tunable Filter Systems

Designing and building an RF amplifier that can boost a low power generated RF signal required by an AOTF crystal that acts as an optical fiber may appear to be easy for experienced RF designers. However, the special conditions required for space-based scientific instruments make this task an interesting challenge.
