Surface acoustic wave (SAW) filters are key components in RF filters, typically applicable to radio frequency (RF) and microwave circuits. B39211B3646Z710 is a type of SAW filter, used to select or reject specific frequencies while allowing the remaining to pass. It is a wide band pass filter with center frequency of 3GHz, and bandwidth of 2.2GHz. It is currently used in a variety of communication applications for both commercial and military purposes.

Application Field

The B39211B3646Z710 SAW filter has various application fields, such as:

• Mobile communication- mobile phones, WCDMA, LTE, CDMA and GMS
• Telecommunication- base stations and wireless local loops
• Consumer electronics- GPS receivers, satellite broadcasting receivers, and transceivers

These are just a few of the application fields in which this SAW filter can be used. Other applications include test and measurement equipment, automotive radar, radar jamming, and military communication systems.

Working Principle

The B39211B3646Z710 SAW filter is based on a single reflective SAW structure, which uses surface acoustic wave (SAW) as the carrier frequency. The filter is constructed on a piezo-electric substrate, such as quartz, using the piezo-electric effect to convert the incoming electrical signal into a physical movement of the substrate. The incoming signal is then transformed into a series of acoustic waves, which travel across the substrate\'s surface. When the waves reach the end of the substrate, they are reflected back to the original starting point. Along the way, the wave passes through a series of electrically controlled transducers, which allow only certain frequencies to pass through. The frequencies that are filtered out are rejected, and the frequencies that are allowed to pass are passed on to the output.

In conclusion, the B39211B3646Z710 SAW filter is a wide band pass filter with center frequency of 3GHz, and bandwidth of 2.2GHz. It has many application fields, such as mobile communication, telecommunication, consumer electronics, and so on. The working principle of the filter is based on a single reflective SAW structure, which uses surface acoustic wave (SAW) as the carrier frequency.
