Custom Built LC Filters - 10 KHz to 5.0 MHz

lpflh

Allen Avionics manufacturers Lowpass Highpass and Bandpass 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.
All the filters in the Low Profile Series are a maximum of 1/2 inch high to accommodate modern high density, low profile circuit board design. For Lowpass Highpass and Bandpass Filters above 5 MHz our subminiature filters are a perfect choice.

  • Frequency Range: 10 KHz to 5 MHz

  • Impedance Range: 50 Ohms to 2.5K Ohms

  • Construction: Sealed in metal cans with P.C. terminals

  • Delivery: Prototypes can often be delivered in less than 7 days.
