mcolpPrinter

Allen Avionics manufacturers Lowpass 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: 50 Hz to 5000 MHz

  • Impedance Range: 50 Ohms to 50K Ohms

  • Construction: Epoxy encapsulated or sealed in metal cans

  • Available Connectors include BNC, SMA, Type N, Printed Circuit and Surface Mounting.

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

  • Maximum Ripple: .25dB

  • Maximum Insertion Loss: 1dB

  • Custom Packages and Mounting are available, FAX or E-Mail your requirements

Order any Cut-Off Frequency from 50 Hz to 5000 MHz. Interpolation between tabulated data allowable.

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. Epoxy cases available where listed in table.
