HF-Band LC Band Pass Filter, 5MHz

ABPF-5MBW5M-01 is a 50Ω Band Pass Filter in a connectorized package. The bandpass filter has a center frequency of 5 MHz and a 1 dB passband bandwidth of 5MHz. The 1-dB passband  frequency is 2.5 MHz – 7.5 MHz. The filter is constructed using high-Q inductors and capacitors, hence  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: 2.5 – 7.5 MHz
  • Pass band insertion loss: 2.5dB max
  • Passband VSWR: 1.5:1 max
  • Rejection: >40dB @ 1.3MHz and 8.7MHz
  • Connectors: SMA-F

ABPF-5MBW5M-01 is a miniaturized descrete component band pass filter operating in the HF Band. It has a passband frequency of 2.5-7.5MHz. ABPF-5MBW5M-01 is a band pass filter that is built using high-Q inductors and capacitors to achieve low insertion loss and high stop-band rejection. HF Band refers to the radio frequency electromagnetic waves in the 3-30MHz spectrum. This band is popular among many HAM radio hobbylists. It is also known as  amateur radio and is popularly used for of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, and emergency communication. ABPF-5MBW5M-01 is an LC band pass filter that is designed to operate in a sub-band of the HF-Band spectral space.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 other HF-band signals above 7.5MHz 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 2.5 - 7.4 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-5MBW5M-01
