50Ω
20 to 4500 MHz
The Big Deal
• Low insertion loss, 1.5 dB typ.
• Low unbalance, 0.2 dB, 2°
• Power handling up to 0.4W
CASE STYLE: DB1627
Product Overview
Mini-Circuits TCM3-452X+ is a 50Ω surface mount balanced transmission line transformer with a 3:1 sec-
ondary/primary impedance ratio covering the 20 to 4500 MHz band. This model handles RF input power
up to 0.4W and provides low insertion loss, good return loss, and low amplitude unbalance. Measuring
only 0.16 x 0.15 x 0.16”, the unit features core and wire, all-welded construction mounted on a six-lead
plastic base. The unit also includes Mini-Circuits’ Top Hat® feature for faster, more accurate pick-and-
place assembly.
