Bandpass Filter

Product Information


POC’s Agile Bandpass Filters (ABF) utilize technology similar to ANF. They employ a novel filter architecture that is rapidly tunable, with vastly improved power handling, resulting in a compact and inexpensive bandpass filter. It has been tested for frequency ranges from 300 MHz to 1 GHz, and can be improved to work beyond 8 GHz. They are especially suited for Software Defined Radio systems, acting as a pre-selection filter for the receiver.


  • Reduces in-band interference from EW Assets or other external noise sources
  • Sharp roll-off factor provides high RF isolation, enabling Simultaneous Transmit and Receive (STAR)
  • By limiting the signal spectrum to the operating band, it maximizes receiver sensitivity and dynamic range
  • Low insertion loss minimizes the need for remedial amplification
  • Fast tuning speed supports military radio frequency hopping rates
  • Can be coordinated with interference sources and agile notch filters for unprecedented communications assurance
  • Flat passband and linear phase response create a filter that will not affect waveform quality
  • Lightweight, small, and inexpensive, low risk technology
