The device is specifically designed to increase SNR performance while simultaneously reducing the overall system noise level. It also features an adjustable gain range, and adjustable passband characteristics, making it suitable for a wide range of applications.

Application Field

The LTC1064-4CN#PBF has a wide range of applications including high frequency digital communication, radar and television systems, datacom and telecommunications, RF test and measurement, satellite communications and instrumentation. It can be used as a multi-function SAW filter in any of these systems, providing superior performance and increased SNR compared to traditional active SAW filters.

Function & Working Principle

The LTC1064-4CN#PBF is a single-channel active SAW filter, with an adjustable gain range, passband characteristics and low noise CCD active filter integrated with the SAW filter. The primary function of the device is to amplify, filter and improve SNR performance. The device works on a principle known as surface acoustic waves, which are high-frequency waves that travel along the surface of a solid material, such as a silicon substrate. In the case of the LTC1064-4CN#PBF, the surface acoustic waves are generated by an active CCD filter and transferred to the SAW filter, where they are amplified and filtered.

The SAW filter amplifies the incoming signal, which improves the signal-to-noise ratio and increases sensitivity. This higher sensitivity reduces the noise in the system, resulting in improved performance. Furthermore, the SAW filter can be adjusted to pass different frequencies, allowing for various applications.

Advantages

The LTC1064-4CN#PBF offers several advantages over conventional active filters. Its amplified and filtered output offers much better signal-to-noise ratio performance than a conventional filter. Its adjustable gain range and passband characteristics allow for more flexible applications. Additionally, its low-noise CCD active filter helps to further reduce system noise levels.

Drawbacks

The main drawbacks of the LTC1064-4CN#PBF are that it is relatively expensive and difficult to use for the novice user. Additionally, it requires a specific power supply for operation.

Conclusion

The LTC1064-4CN#PBF is a high-performance, single-channel active SAW filter. It is designed to amplify and filter signals in order to achieve better signal-to-noise ratio performance. Its primary applications include high frequency digital communication, radar and television systems, datacom and telecommunications, RF test and measurement, satellite communications and instrumentation. Its adjustable gain range and passband characteristics make it suitable for a wide range of applications. The main drawbacks of the device are its cost and the difficulties associated with using it.
