Oven-controlled oscillator shrinks into
flatpack
A compact oven-controlled crystal oscillator comes in a 1in-square flatpack for space applications.
Temex has released a compact oven-controlled crystal oscillator (OCXO) in a 1in-square flatpack for space applications This new low-power-consumption OCXO is designed specifically for synchronisation applications like outer space up/downlink communications where a wide operating temperature range and low energy consumption are critical

SAW oscillators run up to 2GHz
The new QES211 series extends the frequency range of Temex voltage controlled SAW oscillators to 2.0GHz, bringing the size and cost advantages of SAW technology to a wider range of applications.
Low-power OCXO qualified for emergency beacons
The Temex QEO LC93 high-stability oven-controlled crystal oscillator allows designers to reduce the power consumption of emergency locator transmitters and thereby extend transmit time.
It was designed to meet the ESA-SCC3501 specification and complies with MIL-PRF-55310.
This breakthrough product results from Temex's long-standing experience in the design and manufacture of highly stable and precise frequency sources for demanding scientific missions.
Such space missions, like the European Space Agency's Mars Express, require state-of-the-art technology to secure a continuous transmission with high frequency stability.
NASA's International Space Station (ISS) and Galileo program and the ESA's Automated Transfer Vehicle (ATV) are also supported by Temex products.
The frequency stability of this new OCXO has a positive impact on satellite transceiver performances and makes it a smaller, cost-effective solution.
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 the OCXO is available for system validation.
The new low consumption OCXO offers a unique combination of key advantages such as: a frequency range from 30 to 120MHz; nominal stability of +/- 0.1ppm over a temperature range from -25 to +70C (vacuum condition); ageing of +/-2ppm after 15 years; power consumption of 0.3W at 25C in steady state (vacuum condition) from a 9V supply; and a phase noise floor at -155dBc/Hz at 100kHz from the carrier.
"Temex flatpack XO, VCXO and TCXO product ranges are used all over the world".
"This new surface-mount flatpack OCXO frequency source provides the flexibility expected by our customers".
"It is the only OCXO worldwide, providing such high-performances at the same time: low consumption, low phase noise and reduced volume", says Jean Forget, Managing Director of Temex's Defense and Space Business Group.
