Designed and manufactured by Nooelec in North America, with a full 2-year product warranty. \u0026lt;p\u0026gt;Broadcast FM can be particularly problematic due to the high-powered transmitters used for broadcasting in some areas. These signals can overload the front end of an SDR, causing imaging and a number of other issues. \u0026lt;p\u0026gt;We designed Flamingo FM to provide sufficient attenuation for broadcast FM frequencies (\u0026gt;40dB typical) while ensuring adjacent bands, such as the important VHF airband (108-137MHz) are minimally affected. The -3dB rolloff of the filter is 80MHz and 115MHz. Minimal out-of-band insertion loss means the filter can stay in place for most any application. As a true bandstop filter, you are able to pass-through DC (bias power) when it is required. \u0026lt;p\u0026gt;DC current handling is 250mA (min), and the maximum recommended signal level is 18dBm (5Vp-p), so there is no issue using the filter for higher-power applications. Typical performance characteristics can be found on the downloads tab of the product page on our website. \u0026lt;p\u0026gt;Flamingo FM has its filter circuitry fully shielded with an EMI frame, and has its front end protected by an ESD diode meant for RF applications. \u0026lt;p\u0026gt;2 mounting holes are available on the PCB for various mounting options, and the SMA hardware (washer and nut) is included.\u003cbr\u003e\u003cbr\u003e• A high-quality, high-performance bandstop filter designed for software defined radio (SDR) applications. Includes free male SMA-male SMA barrel connector!\u003cbr\u003e• Flamingo FM was designed to provide approximately 40dB attenuation for broadcast FM frequencies, while ensuring that adjacent bands are minimally affected. The -3dB rolloff of the filter is 80MHz and 115MHz, which means the VHF airband (108-137MHz) is minimally affected. The minuscule out-of-band insertion losses means the filter can stay in place for most any application\u003cbr\u003e• The filter is fully EMI shielded, and installed in a custom black anodized aluminum enclosure for further protection and isolation. The front end is protected by an RF-rated ESD diode, which provides protection not just for your filter, but also the radio or SDR behind it\u003cbr\u003e• Flamingo FM is a proper bandstop filter, so you are able to pass-through DC (bias-tee) power when required.
