Introduction

Finding the right SAW filter manufacturer is crucial for reliable RF system design. This guide lists top manufacturers and their product highlights, including TAI-SAW, Qualcomm, API, Golledge Electronics, Oscilent, Amplitronix LLC, Vectron, Filtronetics, Microsaw, SAWTRON, etc.

What is a SAW Filter?

The SAW device which performs filtering operations is known as a SAW filter. Usually, SAW filters operate from 600 MHz to 2 GHz frequency range in mobile environments. Based on IF (Intermediate Frequency) and RF (Radio Frequency) filtering, there are two types: IF SAW filters and RF SAW filters. SAW is the short form of Surface Acoustic Wave.

There are various types of SAW filters based on construction viz. IIDT, DMS, and ladder.

Following are the technical specifications of SAW filters to be considered while buying one for your needs:

  • RF filter or IF filter
  • RF Center frequency
  • Bandwidth
  • Pass Band Ripple (dB)
  • Power handling capability
  • Insertion Loss in pass band (dB)
  • Package type and dimension

The SAW filter has the following advantages or benefits:

  • It allows electro-acoustic coupling via the transducer.
  • Its velocity is 10510^5 times less than EM wave (Electromagnetic wave). This is the major difference between SAW and EM waves. Due to this, SAW filters are used where EM wave based filter designs are impractical to be developed.
  • SAW filters are cheaper compared to BAW (Bulk Acoustic Wave) filters.
  • SAW filters are easy to fabricate due to easy access to their structure from the above surface of the filter.
