NooElec Distill:FM Barebones - Broadcast FM Bandstop Filter for Software Defined Radio Applications

• A high-quality, high-performance bandstop filter designed to attenuate broadcast FM for software defined radio (SDR) applications, with minimal interference to adjacent bands and tiny insertion loss. Bandstop design means the filter will pass DC (bias-t power)
• Makes a great companion to any SDR, but especially RTL-SDRs like our NESDR series, which can be easily overloaded by strong broadcast FM signals
• Distill: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
• Please review the datasheet for full product details! https://www.nooelec.com/datasheets/100758 We want to be sure you buy the right filter for the job :) -3dB rolloff frequencies: 80MHz & 115MHz; attenuation (typical): >40dB; DC current handling: 250mA (min); AC signal level handling: +18dBm (min)
• Designed and manufactured by Nooelec in the United States. Full 2 year product warranty direct through Nooelec

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 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. We designed Distill:FM to provide sufficient attenuation for broadcast FM frequencies (>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. 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: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. 2 mounting holes are available on the PCB for various mounting options, and the SMA hardware (washer and nut) is included.
