Cobham Microwave RF & Microwave Filters - Cobham plc

Cob-flc-066Lumped Element FiltersFEATURES• Center Frequency : 1296 MHz• BandWidth : 1281 MHz to 1311 MHz• Input Power (max) : 0 dBm• Insertion losses @ fo : < 5 dB• Operating temperature : -40°C to +85°CDESCRIPTIONThe cob-flc-066 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.ELECTRICAL SPECIFICATIONSSymbol Unit ValueImpedance Z Ω 50Center Frequency Fo MHz 1296Insertion Loss @ Fo dB < 5Relative Insertion Loss @ Fo ± 7.5 MHz dBc < 0.5-3dB Bandwidth MHz > 30Return Loss in Fo ± 7.5 MHz dB > 17.7Attenuation from DC to 1025 MHz dBc > 50Attenuation from 1359 to 1568 MHz dBc > 20Attenuation from 1569 to 1600 MHz dBc > 70Attenuation from 1600 to 3000 MHz dBc > 50Group Delay Variation in Fo ± 7.5 MHz ns < 5Group Delay Matching @ Fo ns < ± 10APPLICATIONS• Intermediate frequency• AvionicsENVIRONMENTAL SPECIFICATIONSSymbol Unit ValueOperating Temperature range T °C -40 → +85Storage Temperature range T °C -40 → +85OTHER SPECIFICATIONSSymbol Unit ValueDimensions L x l x h inch 1.2x0.5x0.235Weight g 6 ± 0.6ConnectorsSMDCobham Microwave 134
