SAW Filters and the B39389G3962M100

Surface acoustic wave (SAW) filters demonstrate excellent performance characteristics and are widely used in many applications. The B39389G3962M100 is a common example of a SAW filter.

SAW filters are basically a type of acoustic filter which uses surface acoustic waves to filter out unwanted signals, allowing desired frequencies to pass through. They are commonly used in telecommunications, medical, automotive, and industrial applications.

The B39389G3962M100 is a SAW filter designed for use in mobile communication systems. It operates in the band of 450–860 MHz and has a maximum insertion loss of 0.7 dB. Its stopband rejection is greater than 70 dB. It is a wideband filter with a rejection of 250 MHz, and the rated isolation is over 50 dB. The size of the B39389G3962M100 is 10.2 x 12.2 x 2.5 mm.

The working principle of the B39389G3962M100 is to employ a high-Q filter topology based on the lumped-element infinite impedance transmission line (LITL) filter to achieve a wide stopband. Surface acoustic wave (SAW) filters are built using thin-film techniques on piezoelectric materials, which generate surface acoustic waves (SAW).

The B39389G3962M100 can be used in a variety of radio frequency systems, from cellular systems to satellite and space communications. It is used as a transmitter bandpass and receive bandpass filter in mobile communication systems, and it is also a common choice for use in base station filters for pagers, land mobile radios, and two-way radios.
