DC Pass, High Power  
ZDDC-50-521+  
Dual-Directional Coupler  
50Ω 50dB Coupling 400W* 20 to 520 MHz  
The Big Deal  
• High power handling, up to 400W  
• Low insertion loss, 0.1 dB Typ  
• Excellent return loss, 28 dB Typ (In/Out)  
• High directivity, 26 dB Typ  
• Water resistant, IP67  
CASE STYLE: RC2504  
Product Overview  
Mini-Circuits ZDDC-50-521+ is a coaxial high-power (400W) wide band (20-520 MHz) dual-directional coupler  
which features low insertion loss (0.1 dB), 50 dB coupling and excellent mainline return loss (28 dB). The Dual  
directional design allows monitoring forward and reverse power and guarantees good directivity, flatness and  
coupling accuracy.  
The ZDDC-50-521+ supports a wide variety of applications from military to commercial, including GSM  
transmitters and more. The coupler is constructed in a rugged, compact metal case (3.0 x 2.154 x 0.975”) and  
is splash and water resistant, meeting IP67 immersion standard.  
Key Features  
Advantages  
Feature  
High power handling:  
400W @ +85°C  
Usable in many systems with high-power requirements such as  
antenna feeds, power amplifiers, and others that require sampling a  
high power RF signal.  
300W @ +105°C  
Used primarily in high power transmission applications, the excellent  
through-path signal loss maximizes the power transmitted to the  
antenna.  
Low mainline loss, 0.1 dB typ.  
Excellent return loss, 28 dB typ.  
(input and output)  
Provides excellent matching for 50Ω systems.  
High directivity with 50 dB coupling allows accurate signal sampling  
through the coupled port with minimal measurement error.  
High directivity, 26 dB typ  
DC current passing up to 4 A  
Meets IP67 immersion standard  
*See power derating on page 2  
Suitable for use in systems requiring DC voltage on the RF line, such  
as supplying bias to antenna circuitry via the antenna cable.  
Model can handle immersion in water of up to 1m (3.3 ft) for up to 30  
minutes.
