RF1172C SAW Filters

The RF1172C is a low cost SAW (surface acoustic wave) Filters utilizing advanced manufacturing techniques. It provides very high selectivity, low insertion loss, and excellent dynamic range. Ideal for wireless applications, it helps eliminate any undesired signals from the desired signal and is suitable for applications ranging from GSM/CDMA to WiMAX and Wi-Fi.

Application Field

The RF1172C is a SAW filter used in wireless communication systems. It is used as a bank of narrow band filters that help eliminate undesired signals such as GSM or CDMA, as well as facilitate the use of WiMAX and other wireless technologies without interference from the other signals. In addition, RF1172C can also be used in close proximity to baseband electronic components such as amplifiers, power supplies, and other video/audio switching devices.

Working Principle

The RF1172C works on the principle of surface acoustic waves (SAWs) generated by an array of interdigital electrodes on the surface of a substrate. These electrodes act as transducers to convert electrical energy into mechanical energy, which in turn causes waves that propagates along the surface. Due to the dispersive nature of the medium, the frequency content of the signal can then be tuned by adjusting the electrodes parameters such as size, spacing and shape.

The RF1172C has two sets of transducer electrodes; one set is the input set and the other set is the output set. The input signal is processed by the input set of transducers, which generate acoustic waves. These waves then travel through the medium where they are filtered based on their frequency content. Finally, the acoustic waves reach the output set, where they are converted back to electrical signals.

The RF1172C also provides output pins that can be used for signal conditioning. This signal conditioning circuitry helps improve the performance of the filter and also helps reduce the insertion loss. The surface acoustic wave filter also has optional temperature compensation circuitry, which helps maintain the filter performance over wide temperature ranges.

Advantages

The RF1172C has many advantages. First, it is highly selective with low insertion loss. This provides excellent dynamic range and improved signal fidelity. It is also robust and capable of handling high power levels, making it suitable for use in wireless communication systems. Moreover, its temperature compensation circuitry ensures that the filter maintains its performance over a wide temperature range.

The RF1172C also has a low-profile design which makes it ideal for use in tight spaces. Furthermore, it is very low cost and provides excellent value for money. Finally, the surface acoustic wave filter is convenient to use and requires minimal maintenance.

Conclusion

The RF1172C is an ideal choice for use in a variety of wireless communication systems. With its low cost, excellent performance, and small size, it is an attractive option for those looking to improve their system\'s signal quality. The RF1172C\'s surface acoustic wave filter is also convenient to use and requires minimal maintenance, making it an ideal choice for those who don\'t want to spend too much time taking care of their filter.
