SAW filters are useful components which are widely used in many applications including radio frequency (RF) systems. They are designed to reject unintended frequencies while passing those within the desired range. The B39182B9329P810 is an example of a SAW filter which is designed to reject interference from nearby transmitters while passing the desired signal. In this article we will discuss the application field and working principle of the B39182B9329P810.

Application Field

The B39182B9329P810 is a SAW filter designed for use in pTX (Point-to-Multi-Point) systems. This type of system is used to broadcast signals from a single point to multiple locations within a relatively compact area. The B39182B9329P810 is designed to reject interferers from nearby transmitters while passing the desired signal. It is also designed to reject harmonics and spurious signals in order to prevent interference with transmission. The B39182B9329P810 is ideal for applications such as cellular base stations, paging systems, and communication systems operating in the 800MHz-950MHz frequency bands.

Working Principle

The B39182B9329P810 is a surface acoustic wave (SAW) filter based on a piezoelectric quartz substrate. SAW devices have a high Q factor, meaning they have excellent selectivity and can reject undesired frequencies very effectively. The B39182B9329P810 uses interdigital electrodes to generate acoustic waves on a crystalline quartz substrate. The incoming signal is then passed through the filter and the unwanted signals are rejected while the desired frequency is passed through.

The B39182B9329P810 is tuned to a specific frequency by altering the width and pitch of the filters interdigital electrodes. This allows the filter to reject signals outside of the desired frequency range, while passing signals within the desired range. The B39182B9329P810 has a low insertion loss which means that the signal is not significantly degraded while passing through the filter.

In addition to the B39182B9329P810 filter, SAW technology can also be used in resonators, oscillators, and various other applications such as TV broadcasters and satellite receivers. Surface acoustic wave devices have a high selectivity and can be used to reject off-channel signals and undesired harmonics, which makes them an ideal solution for many applications.

Conclusion

In conclusion, the B39182B9329P810 is a SAW filter designed to reject interference from nearby transmitters while passing the desired signal. It is ideal for applications in pTX systems and offers excellent selectivity for rejecting off-channel signals and undesired harmonics. The filter is tuned to a specific frequency by altering the width and pitch of the interdigital electrodes, which allows for the perfect filtering of the received signal. SAW technology is a cost-effective solution which can be used in a variety of applications, making it a popular choice in many industries.
