Nexxim Simulator > Hybrid Coupler, 90-Degree, Ideal
Netlist FormThe ideal coupler model supports frequency domain analysis only, not time domain. An instance of a 90-degree hybrid coupler has the following Nexxim netlist syntax: Axxx n1 n2 n3 n4 [CP=val] [PH1=val] [PH2=val] [RO=val] COMPONENT=hyb90 n1, n2, n3 and n4 are the nodes connected to the coupler. The entry COMPONENT=hyb90 identifies the element as a 90-degree hybrid coupler.
Netlist ExampleA87 11 21 13 44 CP=2.5 PH1=-75 PH2=-205 COMPONENT=hyb90 Notes1. The ideal coupler models support frequency domain analyses only, not time domain. The Nexxim result agrees with the Circuit simulator (HCOM) result at all frequencies. 2. The table below details the operation of the 90 degree couplers. In this table, a=10-0.05CP in dB, A and B are voltages presented at the pins.
