Temex launches ultra-low phase noise RF oscillator

Temex, a world leader in the design and manufacturing of time and frequency solutions, has announced the launch of a new, small RF oscillator in a 51.5mm x 51.5mm x 20.5mm package. This new ultra-low phase noise oscillator is designed for the instrumentation and radar markets.
“This oscillator meets the requirements expressed by various Ministries of Defence in Western countries for their new-generation radar systems that are capable of detecting stealth targets. Test benches should also include this type of very-high-performance oscillator,” says Jean Forget, Executive Manager of Temex’s Defence and Space division.

The new oscillator features several state-of-the-art technical characteristics. It has a frequency of 500MHz (with a possible frequency range of 300MHz to 600MHz), as well as lower phase noise at 10kHz from the carrier (165dBc/Hz). The phase-noise floor is 175dBc/Hz, with the frequency stabilised by temperature control and external control voltage. The unit’s dimensions are 51.5mm x 51.5mm x 20.5mm. The stability is 1ppm in the 0 – 50°C temperature range, with a target of -30°C to +70°C. Its aging is 1ppm / year and, once adjusted in the factory, the oscillator never requires any additional calibration.

The technological progress involved in the development of the oscillator is the product of Temex’s 15 years of experience in the design and manufacturing of extremely stable frequency sources, as well as the company’s unique know-how in the field of SAW resonators. The new ultra-low noise (ULN) sources meet the requirements of the instrumentation and radar markets.

Several prototypes that were sent to major players in the instrumentation and radar markets have achieved very satisfactory and even unexpected results. With the development of ultra-stable frequency sources at 500MHz, a reference for L band and X band sources, Temex is consolidating its development strategy in the fields of advanced high-performance oscillators.

Prototypes of this new 500MHz oscillator with a thermostat-controlled SAW resonator (OCVCSO: Oven Controlled Voltaged Controlled Saw Oscillator), under reference SR W150, will be available for system validations in the second quarter of 2007.

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
