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: 500 Hz to 150 MHz Impedance Range: 50 Ohms to 2.5K 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: 1dB Order any Center Frequency from 500 Hz to 150 MHz. Interpolation between tabulated Center Frequencies and Bandwidth is 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.
