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.

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.
Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...
A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
