Surface Acoustic Wave (SAW) filters are an important type of electronic filter used in wireless communication and satellite systems. They are discrete components that are found in many different applications, but when it comes to high-frequency frequency selection and signal conditioning, they are especially useful. The SF2136E SAW filter is a great example of how a SAW filter can be used in a variety of different applications.

The SF2136E SAW filter is an integrated circuit filter with a frequency range between 0.5GHz and 2.2GHz. It is designed to be used in the 5G wireless communication systems. The filter is adapted to be used in the circular polarisation domain and can be used in different architectures for achieving very high data rates over large bandwidth. It provides very good performance in terms of ACLR (Adjacent Channel Leakage Ratio) suppression, without any significant power penalty. It is ideal for applications such as base station UXRF, base station modem, remote-control systems, LTE, GSM, WCDMA, and Wi-Fi.

In order to understand the SF2136E SAW filter and its working principle, it is important to understand how SAW filters work. SAW filters are made up of two components: a piezoelectric transducer and an acoustic waveguide. The piezoelectric transducer is an electrically conductive surface that is coated with a piezoelectric material such as quartz or lead zirconate titanate. This transducer converts the RF (radio frequency) signal into an acoustic wave which is then passed through an acoustic waveguide. The waveguide is constructed by depositing a thin metal film on the surface of a transparent material such as glass or plastic. This allows the acoustic wave to propagate through the waveguide.

The waveguide only propagates waves that are at a certain frequency and amplitude, so the frequency and amplitude of the wave that is transmitted is determined by the characteristics of the waveguide. By creating waveguides with different frequencies and amplitudes, it is possible to select a specific frequency and amplitude for the desired signals. The signals that have the desired frequency and amplitude are then passed through the SAW filter, while the other signals that are not within the desired frequency and amplitude are filtered out. This allows the SAW filter to attenuate the undesired signals and maintain the desired signals.

The SF2136E SAW filter is designed to provide very low loss performance for providing the desired frequency and amplitude. It can provide nearly 3 dB power loss, which is remarkable for a SAW filter. In addition to this, the filter provides very good ACLR suppression performance and can provide up to -50 dB ACLR at 6 dB bandwidth. The filter also provides very good out-of-band rejection performance for achieving maximum signal level accuracy. Finally, the filter also provides very low phase noise performance for achieving high data rate transmission over large bandwidth.

The SF2136E SAW filter is a great choice for a wide range of wireless communication and satellite systems as it provides the desired performance for achieving maximum signal level accuracy. With its high power and ACLR suppression performance, the filter is ideal for applications that require high data rates over large bandwidth. Therefore, the SF2136E SAW filter is an excellent choice for a wide variety of applications that require precise frequency selection and signal conditioning.
