The center frequency of this filter is 5750MHz, and the 3 dB bandwidth is about 600MHz. It is a multilayer thin-film circuit structure with non-sharp cut-off characteristics. Anti-interference and performance optimization for 5.8G WiMAX, WiFi and other wireless system receiving equipment can effectively filter out out-of-band signals, reduce noise, and increase dynamic range.
