Coaxial Bandpass Filter VBF-1840+ 50 1750 to 1930 MHz The Big Deal * Low Insertion Loss (2.0 dB typical) * Good close-in rejection * Versatile small size, coaxial, 1.43" length CASE STYLE: FF704 Product Overview The VBF-1840+ Band Pass Filter is constructed using internal LTCC Band Pass Filter structure to achieve repeatable performance. Covering 1840 MHz 90 MHz, these units offer low insertion loss and good rejection at the band reject edges. Built using Mini-Circuits proven unibody construction which integrates the RF connectors with the case body, the VBF-1840+ takes very little space and meets rugged test lab system environment. Key Features Feature Advantages Good Rejection close to pass band Provides good rejection of signals close to the pass band, for improved system performance. Compact Versatile Case (1.43"x0.41") Enables use in a variety of applications including space constrained connectorized systems. Connectors: SMA Female (1), SMA Male (1) Rugged Unibody Construction Mini-Circuits Unibody construction allows survivability in critical applications including militarized or industrial systems.
