Product Overview
Mini-Circuits’ ADT2-71T+ is a 50Ω DC isolated surface-mount transformer with a secondary/primary im-
pedance ratio of 2:1 and a center tap on the secondary winding. This model covers the 0.005 to 70 MHz
band with low insertion loss (0.9 dB) as well as low phase unbalance (3˚) and amplitude unbalance (0.5
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.
Key Features
Feature
Advantages
Provides DC isolation between circuits and efficient AC transmission, eliminating the
need for external DC biasing components.
DC isolation
Secondary center tap
Allows DC feed up to 30 mA and DC bias without adding bias tees into the signal chain.
Excellent transmission of signal power from input to output.
Low insertion loss, 0.9 dB
Low phase and amplitude unbalance, 3˚, Low phase and amplitude unbalance can improve a system’s electromagnetic compat-
0.5 dB
ibility by rejecting unwanted common-mode noise.
Small footprint, 0.27 x 0.31 x 0.22”
Accommodates tight space requirements for dense PCB layouts.
