SAW (surface acoustic wave) filters are one of the most common frequency selective circuits used in the modern communication systems. SF1120B is one of the most popular SAW filters, which are widely deployed in several applications that require precision signal filtering and manipulation. This article will firstly explain SF1120B’s working principle and then discuss its application fields.
Working Principle of SF1120B
SF1120B surface-acoustic-wave (SAW) filter is based on the principle of generating acoustic waves on the surface of a piezoelectric substrate. Piezoelectric materials are crystalline materials that can convert electrical energy into mechanical energy, and vice versa. The acoustic wave propagates along the surface of the substrate and interacts with a circuit pattern of interdigital transducers (IDT). The circuit consists of two identical IDTs, one for input and other for output. The filter works as a frequency-selective circuit that passes signals with frequencies above a cutoff frequency and attenuates the others.
In order to achieve the desired frequency selectivity, inductors and capacitors are used in the design. These elements are normally built into the substrate in a process called “bonding”. The properties of these components are determined by the dimensions of the substrate and the parameters of the IDTs. The filter characteristics can also be tuned by adding a series of dielectric layers between the IDTs and substrate. This segmentation of the substrate allows to independently control the cut-off frequency and pass-band gain of the filter.
Application Fields of SF1120B
SF1120B is ideal for frequency-selective applications, such as wireless local area networks (WLANs) and cellular base stations that require precision signal filtering and manipulation. The filter’s high selectivity and low insertion loss makes it a popular choice for use in these applications. It is also used in various communication systems such as cordless phones, satellite systems, etc. Furthermore, it can be used in industrial and domestic applications that require a precision signal filtering.
SF1120B is also well-suited for automotive applications that require precision filtering such as vehicle security systems, car audio systems, and engine control systems. It is designed to be robust and reliable to ensure safe operation in unpredictable and harsh environments. In addition, it can be used in medical drug delivery systems to accurately control and monitor the drug dosage.
Conclusion
In conclusion, surface acoustic wave (SAW) filters are commonly used in communication systems and other applications that require precision signal filtering and manipulation. SF1120B is one of the most popular SAW filters, which is widely used in WLANs, cellular base stations, cordless phones, satellite systems, automotive applications, and medical drug delivery systems. Its working principle is based on the generation of acoustic waves on the surface of a piezoelectric material and its characteristics are determined by the properties of the interdigital transducers (IDTs) on the substrate.
