none

Required

string

 

Notes

1. The following conditions should be satisfied: 0.01 £ W/H £ 100, and Max(W1,W2) £ 0.5×lg, where lg is the guide wavelength.

2. Node numbers can be reversed such that n1 (and associated width W1) is at the wide end of the taper.

3. The taper type is set through the keyword parameter TAPER, such that:
LinWidth: Linear Width
ExpWidth: Exponential Width
LinImp: Linear Impedance
ExpImp: Exponential Impedance

Netlist Form

MSTAPZ:NAME n1 n2 [ n3 ] [ n4 ] R1=val R2=val P=val TAPER=val SUB=label

Netlist Example

MSTAPZ:1 1 2 R1=70 R2=100 P=100MIL TAPER=LinImp SUB=SUB1

where sub1 needs to be defined in the corresponding .sub statement.
