Cobham Microwave RF & Microwave Filters - Cobham plc

Cob-flc-019Lumped Element FiltersFEATURES• Center Frequency : 70 MHz• BandWidth : 64 MHz to 76 MHz• Input Power (max) : 20 dBm• Insertion losses @ fo : < 5.5 dB• Operating temperature : -40°C to +85°CDESCRIPTIONThe cob-flc-019 lumped element filters aredesigned to give the best performance versus size.High Q capacitors and toroidal inductors areused for low losses and very good out of bandattenuations. These filters are low profilecomponents and can be supplied in SMDpackage or SMA version.APPLICATIONS• Intermediate frequency• AvionicsELECTRICAL SPECIFICATIONSSymbol Unit ValueImpedance Z Ω 50Center Frequency Fc (Bw -3dB ) MHz 70 ± 0.3-3dB Bandwidth MHz [ 11 / 13.5 ]Insertion Loss @ Fo = 70 MHz dB < 5.5Ripple @ Fo ± 1.5 MHz dBpp < 0.5Ripple @ Fo ± 4 MHz dBpp < 1.0Return Loss in Bandwith Fo ± 4 MHz dB > 14Absolute delay @ Fo ns 100 ± 20Group delay variation [ Fc ± 4 MHz ] ns < 40Attenuation [ DC - 45 ] MHz dBc > 62Attenuation [ 45 - 58 ] MHz dBc > 42Attenuation [ 82 - 95 ] MHz dBc > 42Attenuation [ 95 - 1030 ] MHz dBc > 62Attenuation [ 1030 - 2500 ] MHz dBc > 40Max CW input power dBm 20ENVIRONMENTAL SPECIFICATIONSSymbol Unit ValueOperating Temperature range T °C -40 → +85Storage Temperature range T °C -55 → +95Damp Heat( 93 ± 3 )% @ ( +40 ± 2 )°C 21 days3 axes, 2 hours/axes, 10 sweeps, 1octave/minute :Vibration ( Sinusoïdal )* 3 mm peak-peak, 10- Ft Hz* 20G, Ft – 2000 HzFt = 60 Hz TypShocks3 axes, 6 direction 100G, 6ms, saw toothSolvent resistance NF EN 60068-2-45 ( CEI 68-2-45 )OTHER SPECIFICATIONSSymbol Unit ValueDimensions L x l x h mm 34.5 x 9 x 6.35Weight g < 20ConnectorsSMDCobham Microwave 120
