Allen Avionics manufacturers Filters using many design types such as: Butterworth, Chebyshev and Elliptic Functions. The filters tabulated on this page are Chebyshev type. Other types can be designed when their special properties are needed.

  • Frequency Range: 400 Hz to 200 MHz

  • Impedance Range: 50 Ohms to 10K Ohms

  • Q Range: .5 to 50

  • Construction: Epoxy encapsulated or sealed in metal cans

  • Delivery: Prototypes can often be delivered in less than 7 days.
    Call or e-mail factory for special sizes

  • Maximum Ripple: 1dB

Order any Center Frequency from 400 Hz to 200 MHz. Interpolation between tabulated Center Frequencies and Bandwidth is allowable.

The size package that each Bandpass filter requires is a function of impedance, shape factor and type of termination or connector that is needed. The sizes listed will provide you with the minimum and maximum size for the combination of shape factor and impedance. Allen Avionics has hundreds of filter packages that are not listed and can be used to custom fit your application.

   

    Bandpass Filters 7.5 MHz - 200MHz

Size (Inches)

Units normally supplied in metal cans for printed circuit mounting (or end terminals). SMA connectors same size. BNC connectors may require larger cans.
