High power handling: 100W @ 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. Dual-Directional Coupler 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. Low insertion loss, 0.15 dB typ Used primarily in high power transmission applications, the excellent through-path signal loss maximizes the power transmitted to the antenna. Excellent return loss, 26 dB typ. (input and output) Provides excellent matching for 50Ω systems. DC current passing, up to 2 A Suitable for use in systems requiring DC voltage on the RF line, such as supplying bias to remote circuit via the antenna cable. Key Features The Big Deal

  • Ultra wide band 225 to 2500 MHz (usable up to 3 GHz)
  • High power handling, up to 100W
  • Low insertion loss, 0.15 dB Typ.
  • Excellent return loss, 26 dB Typ. (In-Out). DDCH-35-252+Dual-Directional Coupler DC Pass, High Power 50 Ω 36 dB Coupling 100W* 225 to 2500 MHz 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. CASE STYLE: PQ2074-1
