The CE10-1R540 is a next generation broadband 1.5GHz to 40GHz, 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 CE10-1R540 offers the best directivity, return loss, and coupling accuracy available on the market. Available as both a three port directional coupler and a four port bidirectional coupler, the CE10-1R540 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 CE10-1R540 package outline drawing is shown below. The CE10-1R540 has input and output ports given in Port Functions. The CE10-1R540 can be used in either the forward or reverse direction corresponding to configuration A and B respectively. For configuration A, input signal into port 1, use port 3 for coupled port, and port 4 for output port. Port two is loaded in the CE10-1R540T and the device can only be used in configuration A.
| Port | Function | Connector Type | Description | DC Equivalent Circuit |
|---|---|---|---|---|
| Port 1 | Input | 2.92F | The input port is DC short to the output port and open to the isolated and coupled ports. |  |
| Port 2 | Isolated | 2.92F | The isolated port is DC short to the coupled port and open to the input and output ports. This port has a factory installed 50 Ohm termination. | |
| Port 3 | Coupled | 2.92F | The coupled port is DC short to the isolated port and open to the input and output ports. | |
| Port 4 | Output | 2.92F | The output port is DC short to the input port and open to the isolated and coupled ports. | |

[1] Amplitude Flatness = Median value of ABS(Measured Coupling Power – Average Coupling Factor).
[2] Coupling loss based on average coupling factor
[3] Excess Insertion Loss = (Input Port to Output Port Insertion Loss) – Coupling Loss.
[4] IL Corrected Directivity = Directivity + Insertion Loss.
