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.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
