Edited by the Electronicstalk Editorial Team on 14 March 2007
Oscillator is ultrastable frequency source
Ultralow-phase-noise RF oscillator is designed for instrumentation and radar markets
Temex has launched a small RF oscillator in a 51.5 x 51.5 x 20.5mm package. This new ultralow-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'.

Oscillators raise frequency and performance
Temex has released a wide range of high-frequency voltage-controlled crystal oscillators (VCXOs) and high-performance oven-controlled crystal oscillators (OCXOs)
'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 oscillator features several state-of-the-art technical characteristics.
It has a frequency of 500MHz (with a possible frequency range of 300 to 600MHz), as well as lower phase noise at 10kHz from the carrier (165dBc/Hz).

Frequency-control components suit WiMAX tasks
Frequency-control components for WiMAX applications include low-phase-noise VCOs, low-phase-noise VC-TCXOs and high-rejection IF SAW filters
The phase-noise floor is 175dBc/Hz, with the frequency stabilised by temperature control and external control voltage.
The unit's dimensions are 51.5 x 51.5 x 20.5mm.
The stability is 1ppm in the 0-50C temperature range, with a target of -30 to +70C.
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 knowhow 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 ultrastable 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 thermostatically controlled SAW resonator will be available for system validations in the second quarter of 2007.
