FM Band 76-108MHz Band Pass Filter (BPF): BPF-76-108

1. For detailed technical parameters, please refer to the following information (1.5-30MHz or 3.5-30MHz or 7-30MHz can also be customized)

2. Input impedance: 50 ohms; output impedance: 50 ohms.

3. The passable bandwidth is 76-108MHz

4. Insertion loss: less than 0.8db

5. TX is connected to the radio, and ANT is connected to the antenna.

6. Power: 100w (SSB CW AM FM) higher power can be customized.

7. Standing wave: less than 1.5

8. Interface: SL16-F (M block) (N block can also be customized)

9. External dimension: 140*53*38mm

Note: With the continuous complexity and harshness of the modern electromagnetic environment, the FM radio has been greatly interfered with. When it is turned on, there is a very noisy back noise, which makes the useful signal submerged, so the China Antenna Network is launched, which is suitable for FM now. The band-pass filter used for stereo radio reception can reduce clutter interference. After installation, it will greatly reduce out-of-band interference.

suitable occasion:

This band-pass filter is suitable for applications that are very close to medium-wave radio stations or are subject to strong medium-wave interference, and can also be used to interfere with FM radio receivers when short-wave radio stations are transmitting. In order to minimize the electromagnetic interference from the surrounding, this band-pass filter can be connected, which will greatly improve the signal-to-noise ratio.

usage:

This bandpass filter can be connected in series between the antenna and the receiver. If you want to receive remote FM stereo stations, you can install an LNA (low noise antenna amplifier) between the filter and the receiver, which is also available in our store. Those who need it can contact the owner.

Special Note: This filter has no effect if the interference comes from within the 76-108MHz passband.
