BPF 88-108
Band-Pass Filter for FM radio band 87.5 - 108 MHz
Description
- BPF 88-108 is an LC band-pass filter.
- Allows the whole band 87.5 – 108 MHz 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 50 x 21 x 45 mm case.
- FME(m) connectors for easy and handy coupling to the surroundings.
- Also available with SMA(f), TNC(f) or BNC(f) connector types. See ordering designations.
- Provided with dual adhesive pad for quick installation.
- BPF 88-108 is lacquered with black vinyl enamel to avoid corrosion.
