The CE10-1R520T is a next generation broadband 1.5GHz to 20GHz, 10dB directional coupler from the Marki Elite Series. Conductive paint is applied to all Elite Series products to reduce EMI/RFI leakage and susceptibility. The CE10-1R520T offers the best directivity, return loss, and coupling accuracy available on the market. Available as a three port directional coupler with included 50Ω termination on the isolated port, the CE10-1R520T is an exceptional choice for broadband return loss measurements, power leveling, and signal monitoring applications. Sophisticated neural network design techniques combined with deep circuit knowledge and triplate stripline construction allow the Marki Elite Series of Couplers to provide superior performance to all other directional couplers available.

A side view of the CE10-1R520T package outline drawing is shown below. The CE10-1R520T has input and output ports given in Port Functions. The CE10-1R520T can be used in the forward direction by configuring the coupler with the input signal into port 1, using port 2 for coupled port, and port 3 for output port.
| Port | Function | Connector Type | Description | DC Equivalent Circuit |
|---|---|---|---|---|
| Port 1 | Forward Power Input and Reflected Power Output | 2.92F | The input port is DC short to the output port and open coupled port. |  |
| Port 2 | Coupled | 2.92F | The coupled port is DC open to the input and output ports. | |
| Port 3 | Forward Power Output And Reflected Power Input | 2.92F | The output port is DC short to the input port and open coupled port. | |
