The Big Deal
• Low Insertion Loss (1.6 dB typical)
CASE STYLE: FF704
• Good close-in rejection
• Versatile small size, coaxial, 1.43" length
Product Overview
The VBF-7900+ Band Pass Filter is constructed using internal LTCC Band Pass Filter structure to achieve
repeatable performance. Covering 7900 MHz 1ꢀ0 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-7900+ takes very little space and meets rugged test lab
system environment.
