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.
