IQD introduce new custom crystal filter product platform

News

IQD has launched a new custom crystal filter product platform at the European Microwave Week 2013. The IQXF-1000 series are a range of band-pass filters with centre frequencies from 1.4 to 200MHz based around fundamental and third overtone mode crystals. These 2 to 12 pole crystal filters can operate over a temperature range of –55 to +85 degrees C with a bandwidth @3dB from ±2kHz and with the passband ripple as low as 0.5dB and insertion loss down to 2.5dB.

 

Proprietary simulation software is utilised to offer prospective customers rapid feedback on their crystal filter application requirements. What makes the design software a competitive advantage is the embedded algorithm that calculates the necessary relationship between critical resonator parameters within the matched set of crystals used in the filter design. To more reliably determine the filter behaviour in production, the algorithm takes into account production equipment process limitations.

The accurate prediction of the interaction of spurious levels between matched crystals, the influence of individual crystal angle variation and the effect of individual motional parameters on composite filter performance creates filter devices with very tightly controlled parameter statistics. Cutting edge accuracy of designs translates into a smooth transition to efficient volume production for all new models.

IQD’s custom crystal filters are ideal for commercial and military grade mobile radios (HF, VHF, UHF, S-band), microwave link data communications, radar scanning in navigation and avionics and medical instruments such as MRI machines.

Further details will be available at IQD’s stand number B270 at European Microwave Week 2013.
