Description For full product details and specifications, please visit the product page at nooelec.com A high-quality, high-performance bandstop filter designed for software defined radio (SDR) applications. Designed and manufactured by NooElec in the United States. Broadcast AM 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. As such, Distill:AM makes a great companion to our Ham It Up series of HF upconverters. We designed Distill:AM to provide sufficient attenuation for broadcast AM frequencies (>40dB typical) while ensuring adjacent bands, such as 160m, are minimally affected. The -3dB rolloff of the filter is 350kHz and 1900kHz. Minimal out-of-band insertion loss means the filter can stay in place for most any application, though we do recommend removing Distill:AM from your setup when not listening to HF frequencies. As a true bandstop filter, you are able to pass-through DC (bias power) when it is required. 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. Distill:AM has its filter circuitry fully shielded with an EMI frame, and has its front end protected by an ESD diode meant for RF applications. 2 mounting holes are available on the PCB for various mounting options, and the SMA hardware (washer and nut) is included.
