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 20 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
20 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.
