FA4720
Five Pole Bessel Absorbtive Low Pass Filter
ADVANCED DATA SHEET
DESCRIPTION
Aeroflex Microelectronics Solutionʼs Bessel filters are designed
for OEM use in high-speed digital networks, fiber optic, and
telecon systems. The FA4720 Series uses an Aeroflex propri-
etary thick/thin film Absorptive filter design that is a 5th order
Bessel polynomial in both attenuation and group delay char-
acteristics. The Absorptive plus Bessel combination result in
optimum BER and Eye Diagram performance.
Aeroflex Microelectronics Solutionʼs state-of-the-art designs and
ISO 9001 manufacturing facilities enable us to provide high
quality product in large quantities.
