Nexxim Simulator > Directional Coupler, 3-Port
Netlist FormAn instance of a three-port directional coupler has the following Nexxim netlist syntax: Axxx n1 n2 n3 [COUP=val]
[LOSS=val] [DIRECTIVITY=val] n1, n2, and n3 are the nodes connected to the coupler. The entry COMPONENT=coupler3 identifies the element as a 3-port directional coupler.
Netlist ExampleAcoup3 11 21 13 COUPL=30 COMPONENT=coupler Notes1. 20 log |S21| = 20 log |S12| = -LOSS 2. 20 log |S23| = 20 log |S32| = DIRECTIVITY 3. 20 log |S31| = 20 log |S13| = -COUP 4. |S11| = (VSWR1 -1)/(VSWR1 + 1), where VSWR1 is the voltage standing wave ratio at port 1. 5. |S22| = (VSWR2 -1)/(VSWR2 + 1), where VSWR2 is the voltage standing wave ratio at port 2. 6. |S33| = (VSWR3 -1)/(VSWR3 + 1), where VSWR3 is the voltage standing wave ratio at port 2. 7. The phase of all S-parameters is zero degrees. HFSS视频教程 ADS视频教程 CST视频教程 Ansoft Designer 中文教程 |
