RF Band Stop Filter Supplier Singapore

Band Stop Filters are sometimes called band elimination filters or notch filters, since they stop a certain band of frequencies. Unlike high pass and low pass filters, band pass and band stop filter applications have two cut-off frequencies.

In other words, they’ll simply pass over and under a certain range of predetermined cut-off frequencies depending on the component values utilized in the circuit design. Any frequencies from these are immediately constricted and they have two pass bands and one stop band.

Characteristics of Band Stop Filters

The functional traits of a band stop filter are exactly the opposite of the band pass filter. In band stop filters, when the input signals are given, the low frequencies then pass through the low pass filter in the band stop circuit. For the high frequencies, they are allowed to pass through the high pass filter in the circuit.

Take ABSF-16M05BW400K-01, , a bandstop filter by AWG Tech, an RF component supplier in Singapore.

ABSF-16M05BW400K-01 is a HF-Band bandstop filter. It has a lower passband from dc – 13.5 MHz and an upper band from 19.4 to 30 MHz. In between 13.5 MHz and 19.4 MHz is the stop band. It has a 40-dB notch bandwidth of 400kHz centered at 16.05 MHz. This means that any signal whose frequency lies between 15.85 to 16.25 will be attenuated by at least 40dB after passing through this filter.

Applications of band stop filter in communication systems

Band stop filter are widely used in many communications systems. Here are a couple of examples presented below:

In a multi-communication systems environment, it is common for a receiver to be subjected to close by strong interfering signals from other systems operating in the same band. This is very common for a GSM base station. In such situations, the best way to remove the spurious is to insert a band stop filer in between the receiving antenna and the receiver.
