416F44011CDR application field and working principle

416F44011CDR is a high-performance surface acoustic wave (SAW) filter developed by Murata Electronics. It is a center frequency (FC) 325.55MHz SAW duplexer, which is composed of two separate SAW filters. The device combines outstanding high-order stopband attenuation with sharp and symmetrical passband response. It encompasses a frequency range of 300MHz to 370MHz, and helps filters facilitate communication systems.

416F44011CDR has a variety of applications, such as wireless transmission, satellite communication and mobile communication, which all require new filter technologies. This device offers benefits such as good selectivity, low insertion loss, good temperature stability, and excellent linearity. It can be used in a range of applications requiring high stopband response, including base station front ends and cellular receiver duplexers.

The operating principle of 416F44011CDR is based on the interference between two acoustic waves, which propagate on the surface of a piezoelectric material. The two waves are excited by interdigitated electrodes, which are deposited on the surface of the piezoelectric material. The piezoelectric effect causes the electrical energy to be converted into acoustic energy, which propagates on the surface of the piezoelectric material. Depending on the input signal frequency, the incident acoustic wave can either be filtered out or pass through the filter.

The working principle is that, when the signal frequency is lower than the center frequency of the filter, the incident wave is filtered out by the SAW filter. On the other hand, when the signal frequency is higher than the center frequency, the incident wave can pass through the filter and reach the output terminal. This method of working provides 416F44011CDR with a good selectivity and low insertion loss.

416F44011CDR is a SAW filter based on surface acoustic wave technology. It has a wide range of applications in wireless transmission, satellite communication and mobile communication systems. Its operating principle is based on the interference between two acoustic waves, which are excited by interdigitated electrodes. It is well-suited for applications requiring high stopband response, and offers benefits such as good selectivity, low insertion loss, good temperature stability, and excellent linearity.
