VBF-1445+

COAXIAL Bandpass Filter 50Ω VBF-1445+ 1420 to 1470 MHz THE BIG DEAL y Low Insertion Loss, 2.0 dB Typ. y Good Close-in Rejection y Versatile Small Size, Coaxial, 1.43" Length y Temperature Stable y Rugged Unibody Construction Generic photo used for illustration purposes only Model No. VBF-8450+ Case Style FF704 Connectors SMA APPLICATIONS y Harmonic Rejection y Transmitters / Receivers PRODUCT OVERVIEW The VBF-1445+ Band Pass Filter is constructed using internal LTCC Band Pass Filter structure to achieve repeatable performance. Covering 1445 MHz ± 25 MHz, these units offer low insertion loss and good rejection at the band reject edges. Built using MiniCircuits proven unibody construction which integrates the RF connectors with the case body, the VBF-1445+ 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 (2) Rugged Unibody Construction Mini-Circuits Unibody construction allows survivability in critical applications including militarized or industrial systems. REV.
