Product Overview
Mini-Circuits’ ADT3-1T-75+ is a 75Ω DC isolated surface-mount transformer with a secondary/primary impedance
ratio of 3:1 and a center tap on the secondary winding. This model covers the 1 to 500 MHz band
with low insertion loss (1.2 dB), excellent return loss (25 dB within the 1 dB bandwidth, low phase unbalance
(1˚) and low amplitude unbalance (0.2 dB). The unit comes enclosed in a miniature, 6-lead plastic
package measuring just 0.27 x 0.31 x 0.22”, ideal for dense circuit board layouts.
