The FA4720 Series uses an Aeroflex proprietary thick/thin film Absorptive filter design that is a 5th order Bessel polynomial in both attenuation and group delay characteristics. The Absorptive plus Bessel combination result in optimum BER and Eye Diagram performance. Aeroflex Comstron’s state-of-the-art designs and ISO 9001 manufacturing facilities enable us to provide high quality product in large quantities. eroflex Comstron - Advanced Optical Filter Modules © SCDFA4720 REV A 10/2/00 Specifications Model Number FA4720-1 FA4720-2 FA4720-3 FA4720-4 FA4720-5 FA4720-6 FA4720-7 FA4720-8 Fc 3dB GHz 1.00 1.30 1.87 3.40 4.30 7.46 10.60 15.00 Fc Tolerance ±GHz 0.05 0.065 0.093 0.17 0.22 0.37 0.53 0.75 Bit Rate Gb/s 1.3 1.7 2.5 4.5 5.7 10 14 20 IMPEDANCE 50 OHMS RETURN LOSS (IN/OUT) > 13 dB to 4xFc for -1 thru -5, to 2xFc for -6 thru -8 INSERTION LOSS @ Fc/10 < 0.10 dB SHAPE FACTOR vs. LOSS Shape Factor (Ratio of F/Fc) 1.50 2.00 3.00 4.00 MAXIMUM INPUT POWER 23 dBm OPERATING TEMPERATURE RANGE 0°C to +85°C Insertion Loss dB (Typical) 7.5 14 28 39 Aeroflex Comstron 2 SCDFA4270 REV A 10/2/00 Plainview NY (516) 752-2357 DB [S12] FA4720-1 0.000 TD [S12] FA4720-1 500.0 Insertion Loss dB Group Delay psec -15.00 200.0 -25.00 0.000 2000 FREQ-MHz 0.000 4000 Insertion Loss and Group Delay DB [S11] FA4720-1 0.000 DB [S22] FA4720-1 Return Loss dB -15.00 -25.00 0.000 2000 FREQ-MHz 4000 Return Loss Aeroflex Comstron 3 SCDFA4270 REV A 10/2/00 Plainview NY (516) 752-2357 Ordering Information Model Number FA4720-1 FA4720-2 FA4720-3 FA4720-4 FA4720-5 FA4720-6 FA4720-7 FA4720-8 Fc 1.00 GHz 1.30 GHz 1.87 GHz 3.40 GHz 4.30 GHz 7.46 GHz 10.60 GHz 15.00 GHz Package See Package Outline PA C K A G E O U TLIN E Custom Packaging Available - Contact Factory Aeroflex Comstrom reserves the right to change at any time without notice the specifications, design, function, or form of its products described herein.
