This product is a 88 to 108MHz limited attenuation band stop filter, which is specially used for the quantitative attenuation of FM FM radio interference for wideband radio receivers such as SDR, and the stopband insertion loss of about 25~35 dB. The strong FM broadcast signal can be attenuated to the appropriate level for the normal use of the high sensitivity receiver. The product is compact and easy to use. It is made of thin PCB and patch components with a strong aluminum alloy shield shell, which is far superior to the filter made from the bare plate PCB.
System impedance: 50 Ohms
Working frequency: 0~4000 MHz
Stopband insertion loss: 25~35 dB @ 88~108 MHz
Out of band loss: < 1dB @ DC to 60MHz & 150 to 2500MHz
Maximum load power: 1 W (30dBm)
Interface: SMA-F, SMA-M (two ends symmetric, no direction)
