Feature:1. Anti FM Interference: When the stopband rejection is greater than 50dB, the filter blocks the broadcast FM band between 88108MHz, with a stopband of 76MHz to 120MHz.2. Filter Out FM: This band stop filter can filter out FM, prevent the short wave from being affected by it, and ensure the purity of its wavelength.3. Small Insertion Loss: The filter can work in the range of 1 to 3000MHz, and the passband insertion loss is less than 1dB, which is very suitable for work use.4. Mini Size: This filter module is very small in size, compact in design, easy to carry, easy to install, and easy to operate.5. PCB Board: The PCB circuit board inside this filter module is exquisitely crafted, responsive, practical and durable.Specification:Item Type: Band Stop Filter ModuleMaterial: PCBOperating Frequency Range: 1-3000MHZCharacteristic Impedance: 50 ohmsStopband: 76-120MHZStopband Suppression: >50dB at 88-108M, anti FM interferencePassband Insertion Loss: <1dBMaximum Input Power: +30dBm (1W)Input and Output Interface: SMA KE (external screw and inner hole).Package List:1 x Band Stop Filter Module
