What is SAW Filter ?
The SAW device which does filtering operation is known as SAW filter. Usually SAW filters operate from 600 MHz to 2 GHz frequency range in mobile environment. Based on IF (Intermediate Frequency) and RF (Radio Frequency) filtering, there are two types viz. IF SAW filter and RF SAW filter. SAW is the short form of Surface Acoustic Wave. There are various types of SAW filter based on construction viz. IIDT, DMS and ladder. Refer RF SAW filter basics>> for more information.
Following are the technical specifications of SAW filter to be considered while
buying one for your need.
• RF filter or IF filter
• RF Center frequency
• Bandwidth
• Pass Band Ripple (dB)
• Power handling capability
• Insertion Loss in pass band(dB)
• packege type and dimension
The SAW filter has following advantages or benefits:
• It allows electro-acoustic coupling via the transducer.
• It's velocity is 105 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 compare to BAW (Bulk Acoustic Wave) filters.
• SAW filters are easy in fabrication due to easy access to their structure
from the above surface of the filter.
