Saw filters

sawfilters SAW components are key elements for wireless transmission. Front-end filters eliminate interference from the incoming RF signals in receivers, thus increasing selectivity and sensitivity of short-range devices. Resonators provide stable frequencies for the RF carrier signals of remote control applications, or for local oscillators of superhet receivers. The crystal structure of support influences greatly on saw components characteristics.

Advantages of Epcos SAW filters using:
  • SAW filters are being produced in SMD ceramic and automotive CSSP package
  • SAW resonators are being produced with tight frequency tolerances:±25/±50 kHz
  • Identical pinning for all standard frequencies in each package size
  • 100% final examination
  • Operating temperature range from –40 °C up to +125 °C
  • Patented passivation technologies for enhanced reliability
  • Component qualification to automotive test procedure AEC-Q200
  • Full level 3 PPAP available
  • Unique production know-how and volume benefits from the world market leader in SAW components
  • RoHS compliant (2002/95/EC)
  • Lead-free soldering compatible with J-STD 20C

The application of SAW filters is preferrable at frequencies from1 MHz to 3 GHz and at losses from 20 to 2 decibel and less. The low border of frequency band can vary depending on support's sizes and technology interdigital transducer. SAW components effectively complete tasks on signal processing at determined frequencies and complicated tuning. At the same time they are characterised by a high selectivity, small sizes ans weight, compatibility with integral modules.

When choosing Saw filters following characteristics are important:
  • Center frequency
  • Frequency band
  • Inserted losses
  • Selectiveness
Among companies producing a wide range of saw components one can note Epcos. The Epcos components are characterised by a perfect reproducing and stable parameters, high reliability, relatively low cost, longer useful life. More over the company has achieved great results in the field of components miniaturization. In such a case saw filters are being produced in small sizes saving improved characteristics when operating.
