FM-Band LC Band Pass Filter

ABPF-98MBW20-01 is a 50Ω Band Pass Filter in a connectorized package. The bandpass filter has a passband frequency from 88 MHz to 108 MHz, offering excellent passband VSWR, low passband insertion loss and high rejection in the stop bands. The filter is designed using high-Q capacitors and wire-wound air coil inductors to ensure the lowest possible passband insertion loss and steep rejection roll-offs. Every unit is 100% inspected and tested during production to ensure repeatable performance across production lots and consistent performance across temperature.

Key Features:

  • Passband Frequency: 88-108MHz
  • Passband insertion loss: 2 dB max
  • Rejection: >40 dB at 70MHz and 140 MHz
  • Connectors: SMA-F

The FM broadcast band is a range of radio frequencies used for FM broadcasting by radio stations. The range of frequencies used differs between different parts of the world.

ABPF-98MBW20-01 is an LC band pass filter that is designed to operate in the FM-Band spectral space between 87-108 MHz. This band pass filter is often inserted between the antenna and the receiver to allow the receiver to reject out-of-band interfering signals such as HF signals and signals from mobile communication networks such as GSM signals. Without the band pass filter, these interference may cause receivers to saturate and will not be able to decode in-band signals from 88-108 MHz.

ABPF-98MBW20-01 is an FM-Band band pass filter that is built using high-Q inductors and capacitors to achieve low insertion loss and high stop-band rejection.

Benefits of using ABPF-98MBW20-01

  • Low cost -ideal for low budget
  • Small size - does not take up a lot of real estate
  • Excellent Rejection characteristics - rejects unwanted spurious signals
  • Ease of use - fitted with SMA-female connectors makes it easy to interface to antenna and for test setups
  • Well matched - Good passband VSWR provides excellent input and output port matching
  • High reliability - Low probability of field failures


Applications of FM-Band Band Pass Filter

  • FM Receivers
  • Test Equipment
  • Military Radio
  • Harmonic rejection
