Product Description

Product Description

450-512MHz Cavity Filters(N Female, 10W, IP60)
 

Cavity filters are the basic circuitry behind a Duplexer and are sharply tuned resonant circuit that allow only certain frequencies to pass.Cavities are often grouped in series with each other to increase
filter effectiveness by making the passband "deeper" with respect to surrounding frequencies. This can be very useful when ham repeaters are situated very close to other spectrum users such as pager whose unwanted signals can interfere with the ham equipment. Cavity filters are a very effective way to create a "notch" at the repeater frequencies.
Topwave model TPW-BPF-4551-NF, a typical UHF cavity filter with low insertion loss and good rejection. Such low band filter widely in LNA and BDA systems, also it is a customize product. Topwave telecom is willing to provide ODM service according to your solutions and systems.
