BPF 118-137
Band-Pass Filter for the air band 118 - 137 MHz
Description
- BPF 118-137 is an LC band-pass filter.
- Allows the whole 118 – 137 MHz band to pass.
- Series coupled high/low pass filter design.
- Chebychev characteristic ensures low insertion loss and high out-of-band rejection.
- Can be used as transmitter filter to prevent out-of-band and harmonics radiation.
- Can be used as a preselector filter to protect a receiver against interferences from transmitters normally being outside the band-pass range.
- Very small dimensions, mounted in a 48 x 50 mm box.
- FME-male connectors for easy and handy coupling to the surroundings.
- Also available with TNC(f), BNC(f) or SMA(f) connectors types.
- Provided with dual adhesive pad for quick installation.
- BPF 118-137 is lacquered with black vinyl enamel to avoid corrosion.
