Introduction to Helical Filters

Helical filters are special types of filter circuits that use elements having a physical shape which is helical in nature. These filters are designed to provide enhanced performance and a wide range of applications due to their unique characteristic. In this article we will discuss the particular model #5HW-88560A-914, its application field and its working principle.

What is a Helical Filter?

A helical filter is essentially an electronic device designed to separate signals that contain different frequencies. It is composed of coils of wire wrapped in a helical shape in order to form an inductance. The helical filters are used in many circuits that require a broad frequency range and superior signal to noise ratio. Various parameters can be adjusted in a helical filter and its components include resistors, capacitors as well as cores.

#5HW-88560A-914 Application Field

The #5HW-88560A-914 model of helical filter is particularly designed for communications, radar and instrumentation. It is well suited for applications in the 400~1000MHz range. Its center frequency is 549MHz, while the 3 dB bandwidth is approximately 17MHz. Moreover, this filter has a high level of rejection compared to other filters in the same class.

How Does the #5HW-88560A-914 Work?

The #5HW-88560A-914 works by using inductive elements and capacitors, so as to filter out undesired signals while at the same time amplifying the desired ones. The filter is designed to isolate available signals and amplifying a specific frequency. This can be helpful in increasing the signal to noise ratio or the signal immunity from nearby sources of interference. The own desired frequency is maximized while the rest are minimized due to the combined effect of the inductors and capacitors in the filter.

Conclusion

Helical filters offer many advantages when compared to conventional filter circuits. They offer improved performance, better signal to noise ratio, superior frequency selectivity and a wider frequency range. The #5HW-88560A-914 model of helical filter is specifically designed for use in communications, radar and instrumentation, and is capable of providing high level of rejection. Furthermore, it works by using inductive elements and capacitors, so as to filter out undesired signals and amplifying the desired ones.
