Narrow Band Linear Phase Bandpass

Custom Built LC Filters - 1 KHz to 80 MHz

nblpbp

The Allen Avionics filters tabulated on this page are the result of state of the art computer aided network synthesis and offer the best compromise in fast roll off, delay linearity, size and cost.

  • Type: Synthesized type offering excellence in fast cut-off and low delay variation characteristics.

  • Frequency Range: 1 KHz to 80 MHz

  • Impedance Range: 50 Ohms to 10 KOhms

  • Q Range: 2 to 50

  • 3 dB Bandwidth: .02 to .5 x Center Frequency (Fo)

  • Construction: Sealed in metal cans

  • Maximum Ripple: .5 dB

Order any Center Frequency from 1 KHz to 80 MHz. Interpolation between tabulated Center Frequencies and Bandwidth is allowable.

 Fo = (F1 + F2)  =  (F3 + F4)  = (F5 + F6)
Approximate Passband Delay (sec.) = Delay (D) / 2 x
π x FC (Hz)
Tabulated delay distortion (%) is defined as the maximum delay difference (%) between any two points within the 3dB passband.
