Features 1、Anti FM Interference: When the stopband rejection is greater than 50dB, the filter blocks the broadcast FM band between 88‑108MHz, 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.
