The Big Deal
• Wideband, 40 to 1250 MHz
CASE STYLE: AT1521
• High impedance ratio, 4:1
• Balanced to balanced configuration with secondary center tap
Product Overview
TC4-122-75X+ is a 75Ω surface-mount balanced to balanced transformer covering the 40 to 1250 MHz band, supporting band-
width requirements for DOCSIS® 3.1 compliant systems and equipment. The transformer provides a 4:1 secondary/primary
impedance ratio with 1.4 dB insertion loss, 1.1 dB amplitude unbalance, and 7° phase unbalance. Featuring core and wire
construction on a 5-lead plastic base with tin over nickel termination finish, the unit measures 0.15 x 0.15 x 0.16”, accommodat-
ing dense circuit board layouts. It also incorporates Mini-Circuits’ Top Hat™ feature for faster, more accurate pick-and-place
assembly.
