DC Pass, High Power

DDCH-50-521+

Dual-Directional Coupler

50Ω 50dB Coupling 300W 20 to 520 MHz

The Big Deal

• High power handling, up to 300W

• Low insertion loss, 0.07 dB Typ

• Excellent return loss, 35 dB Typ (In/Out)

• High directivity, 21 dB Typ

CASE STYLE: PQ2100

Product Overview

Mini-Circuits DDCH-50-521+ high-power dual-directional coupler provides high power handling up to 300W

and insertion loss of 0.07 dB Typ with 50 dB coupling. Covering frequencies from 20 to 520 MHz, it supports a

wide variety of applications from military to commercial, including GSM transmitters and more.

High directivity of 21 dB provides accurate sampling from the coupled port, and typical input/output return loss

of 35 dB provides excellent matching over full frequency range. The coupler is designed into an open printed

laminate (1.0 x 1.5 x 0.128”) with wrap-around terminations for good solderability and easy visual inspection.

Key Features

Advantages

Feature

Used primarily in high power transmission applications, the excellent

through-path signal loss maximizes the power transmitted to the

antenna.

Low mainline loss, 0.07 dB typ.

Usable in many systems with high-power requirements such as

antenna feeds, power ampliﬁers, and others that require sampling a

high power RF signal.

High power handling, up to 300W

Excellent return loss, 35 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, 21 dB typ

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

as supplying bias to antenna circuitry via the antenna cable.

DC current passing up to 4 A
