This family of filters is similar to the
VFL and MVFL Series and is intended for use at the output of a
digital to analog converter. Its special feature is that amplitude
equalizers have been incorporated to shape the passband for sin x/x
correction. The filters below are tabulated for systems using
sampling frequencies of 10.74 MHz and 14.32 MHz.
Allen Avionics can custom design this
type of filter for other cutoff frequencies and sampling rates
VSL Size:

Impedance
= 75 Ohms
Attenuation
= 40 dB or greater at 1.375 x the cutoff frequency
Amplitude
Deviation = ±0.2 dB to the filter passband edge
Maximum
Insertion Loss < 2.5 dB at 10 KHz
