*Note: “A” is the amplitude of the applied signals. When two quadrature signals with equal amplitudes are applied to the coupler as described in the table, they will combine at the output port. If the amplitudes are not equal, some of the applied energy will be directed to the isolated port. Typical Performance Data (@25)

eDscription of Measured Specifications
Parameter VSWR Return Loss
Description
Voltage standing wave rao, the impedance match to 50, the ideal value is 1:1.
Loss of signal power resulng from the reecon caused by disconnuity of transmission line.
Insertion Loss The input power divided by sum of power at the coupling port & transmission port.
The input power divided by the power at coupling port. Coupling Transmission The input power divided by the power at transmission port.
The power at the coupling port divided by the power at the isolated. Directivity
Test Method
1. Calibrating your vector network analyzer.2. Connect the VNA 4 Port to DUT respectively.
3. Measure the data of coupling through port 1 to port 4(S41).4. Measure the data of transmission through port 1 to port 2(S21).5. Measure the data of isolation through port 1 to port 3(S31).6. Measure the data of return loss port 1, port 2, port 3 & port 4.7. According to the above data to calculate insertion loss, directivity.
