CASE STYLE: PQ2100

Product Overview

Mini-Circuits DDCH-50-13+ is a high-power (300W), wide band (20-1000MHz) dual-directional coupler which

features low insertion loss (0.15 dB), 50 dB coupling and excellent mainline return loss (30 dB). The Dual

directional design allows monitoring forward and reverse power and guarantees good directivity, ﬂatness and

coupling accuracy.

The DDCH-50-13+ supports a wide variety of applications from military to VHF/UHF radio, various cellular

base station applications and more.

The coupler is fabricated using laminated PCB process (1.5 x 1.0 x 0.128”) and includes wrap-around

terminations for good solderability and easy visual inspection.

Key Features

Advantages

Feature

High power handling:

300W @ 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.

160W @105°C

Ideally suited for simultaneous monitoring of both forward and reverse

power of a system, and reﬂectometer measurements. The Directivity is

not aﬀected by coupling ports mismatch.

Dual-Directional Coupler

Used primarily in high power transmission applications, the excellent

through-path signal loss maximizes the power transmitted to the

antenna.

Low insertion loss, 0.15 dB

High directivity, 24.5 dB

High directivity with 50 dB coupling allows accurate signal sampling

through the coupled port with minimal measurement error.

Excellent return loss, 30 dB.

(input and output)

Provides excellent matching for 50Ω systems.

Suitable for use in systems requiring DC voltage on the RF line, such

as supplying bias to remote circuit via the antenna cable.

DC current passing, up to 4 A
