In the Telecommunications industry using radio frequencies to transfer data in the form of audio, videos, text and other forms, one of the most important tasks is to limit and separate the frequencies. Sometimes you have to amplify the frequencies or convert it in another form. A wide range of devices are used in this process, and Band Pass Filters and Cavity Diplexers are two devices that filter or separate the frequencies. Here is the difference between both of them –Band Pass Filter
There are three types filters: one that let only lower frequencies pass, and it is called low pass filter, the second let only higher frequencies pass, and it is called high pass, and the band pass filter is one that allows only the frequencies of the selected band to pass. It keeps the unwanted ones away from the system.Cavity Diplexer
Transceivers are a combination of a transmitter and a Receiver and you need to keep the frequencies that are received and transmitted separate. The Cavity Diplexer does the task well while sharing the common antenna for working. It is a three port device used on all duplex transmissions, and is offered for all bands ranging from HF to millewaves.
One common thing between them is that they both control the frequencies but solve different purposes. You can purchase both Band Pass Filters and Cavity Diplexers from Raditek Inc see www.raditek.com for a wide range of variants of both of them. Contact firstname.lastname@example.org for full details.
