Product Overview
Mini-Circuits DDCH-35-252+ is a high-power (100W), ultra wide band (225-3000MHz) dual-directional coupler
which features low insertion loss (0.15 dB), 36 dB coupling and excellent mainline return loss(26 dB). The Dual
directional design allows monitoring forward and reverse power and guarantees good directivity, flatness and
coupling accuracy.
The DDCH-35-252+ supports a wide variety of applications from military to UHF radio (covering all UHF
bands), various cellular base station applications and more.
The coupler is designed into an open printed laminate (1.0 x 1.0 x 0.128”) with wrap-around terminations for
good solderability and easy visual inspection.
Key Features
Advantages
Feature
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:
100W @ 85°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 typ
Excellent return loss, 26 dB typ.
(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 2 A
