Coplanar Bend

The C_BNED module represents a rectangular bend between two coplanar lines. The dimensions of lines are defined using data items addressed by C_ LTYP1 and C_TYP2. The dimensions of the air-bridges at ports are defined in data items addressed by C_BTYP1 and C_BTYP2.

Parameters  

Parameter Description
C_LTYP1 ID of coplanar transmission line applied at ports 1
C_LTYP2 ID of coplanar transmission line applied at ports 2
C_BTYP1 ID of air-bridge type applied at port 1
C_BTYP2 ID of air-bridge type applied at port 2
C_SUB ID of coplanar substrate definition
C_GRID ID of simulation control data
TEMP ID of element temperature definition used for noise computation

Notes

Equivalent Circuit  

For the modeling of the C_BEND element, a p-network is used. The equivalent circuit parameters are derived from quasi-static FD-calculations. The losses (metal losses as well as dielectric losses due to the dielectric layer used for the bridges) within the bend itself are taken into account. The connected lines at ports are modeled as C_LIN elements and are represented by their characteristic impedance ZL and phase constant b. There is no limitation due to the length of connected lines (L in selected C_BTYP).
