Medium Cut-Off High Pass Filters
Custom Built LC Filters - 100 Hz to 1000 MHz
mcohpPrinter

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: 100 Hz to 1000 MHz

  • Impedance Range: 50 Ohms to 20K Ohms

  • 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: .5dB

  • Maximum Insertion Loss: 1dB

Order any Cut-Off Frequency from 100 Hz to 1000 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.
