Cobham Microwave RF & Microwave Filters - Cobham plc

Cob-flc-002Lumped Element FiltersFEATURES• Center Frequency : 12 MHz• BandWidth : 11.2 MHz to 12.8 MHz• Input Power (max) : 20 dBm• Insertion losses @ fo : < 3.5 dB• Operating temperature : -40°C to +80°CDESCRIPTIONThe cob-flc-002 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 MHz 12Bandwidth @ Fc ± 0.6 MHz dBc < 3.5 Typ. < 3.2Insertion loss @ Fc MHz dB < 3.5 Typ. < 3.2Return loss @ Fc dB > 14Attenuation from DC to 8.4 MHz dBc > 60Attenuation from 8.4 to 10.8 MHz dBc > 20Attenuation from 13.2 to 15.6 MHz dBc > 17 Typ. > 19Attenuation from 15.6 to 250 MHz dBc > 53 Typ. > 56Max CW input power dBm 20ENVIRONMENTAL SPECIFICATIONSSymbol Unit ValueOperating Temperature Range T °C -40 → +80Non operating Temperature Range T °C -45 → +95Storage Temperature Range T °C -45 → +85Thermal shock-40°C to +80°C in 5 mn for accumulation of 1000 cyclesHumidity 95 %30G peak at all 3 axes : operatingShocks20G for 9 msec sawtooth : operating40G for 9 msec sawtooth : non operatingVibrations20 G, 20 to 2000 Hz in all 3 axes for 10mn operatingAcoustic Noise150 dB, 50 to 8000 Hz for 60 mnOTHER SPECIFICATIONSSymbol Unit ValueDimensions L x l x h Inch 1.0x0.38x0.38Weight g 8.5 ± 1ConnectorsSMDCobham Microwave 112
