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.
The high quality and reliability required for space applications is achieved through Temex's precision manufacturing abilities and rigorous test procedures developed to simulate extreme conditions and meet MIL and ESA standards.
Temex's custom design service provides a variety of crystal filters covering the frequency range from 1.4 to 300MHz and from 2 to 12 or more poles.
Filter types available include Butterworth, Chebyschev, Cauer and Bessel, with a choice of materials that includes quartz, langasite and tantalate, enabling Temex to address a variety of specifications, especially those requiring wide bandwidths.
All devices are designed to operate in extreme environmental conditions in temperatures ranging from -55 to +125C, making them ideal for satellite applications but also suitable for space probes, military aircraft, military radio, radar, and mobile communications designs.
