Temex of France, a specialist in the field of high-performance time and frequency components and sub-systems, has launched a small-size Oven Controlled Crystal Oscillator (OCXO) in a 25mm x 25mm flat-pack package for space applications. This new low-consumption OCXO is designed specifically for applications such as deep-space up/down link transceivers where a wide operating temperature range and low energy consumption are critical.“
Designed to meet the ESA SCC3501 specification and in accordance with the MIL-PRF-55310 standard, the new low-consumption OCXO offers key advantages such as a frequency range of 30 to 120 MHz; a small size of just 25mm x 25mm x 17mm; a stability of ±0.1ppm nominal over a temperature range of -25°C to +70°C (vacuum condition); ageing of just ±2ppm after 15 years; consumption of only 0.3W at 25°C in steady state (vacuum condition); a supply voltage of 9 volts; and a phase noise floor at -155dBc/Hz at 100KHz from the carrier.
The frequency stability of this new OCXO has a positive impact on satellite transceiver performances. The transmission range is secured by the higher stability of the frequency and the low energy consumption is a mandatory requirement for space-borne equipment. A breadboard model or an engineering model of this new OCXO are available for system validation.

Shape matters when light meets atom

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
