Surface acoustic wave (SAW) filters are one of the most commonly used filters in electronic circuits. They are widely used in a variety of applications, ranging from radio to mobile communication systems. The B39389J1956M100 is a type of SAW filter that is designed for use in the field of communication systems. This paper will discuss the application field and working principle of the B39389J1956M100 SAW filter.

The B39389J1956M100 is a multi-mode filter that can be used for both transmit and receive applications. The filter is designed to provide a low-pass response with a sharp cutoff frequency. This allows for a wide range of applications in radio communications. For instance, the filter can be used for base station applications that require strict filtering of unwanted signals. Additionally, the filter is used in mobile communications, such as cellular telephone systems, to filter out interference from other users and reduce noise.

The working principle of the B39389J1956M100 SAW filter is based on the use of surface acoustic waves. These waves are generated by a metal interconnect structure known as an interdigital transducer (IDT). An input signal is incident upon the IDT, which generates surface acoustic waves that propagate along the surface of the filter. At the output of the filter, a resistor-capacitor (RC) network is used to convert the surface acoustic waves into an electrical signal that can be amplified and used for communication purposes. The filter is constructed from high-temperature co-fired ceramics (HTCC) which make it suitable for use in rugged environments.

In summary, the B39389J1956M100 SAW filter is designed for use in a variety of communication systems. It is a multi-mode filter with a low-pass response and sharp cutoff frequency. The filter works by using surface acoustic waves generated by an interdigital transducer and converted to an electrical signal by an RC network. The filter is constructed from high-temperature co-fired ceramics which makes it suitable for use in rugged environments.
