【Impedance matching circuit design function】
It designs the circuit to convert the impedance of Z=R+jX［Ω］ to a different impedance (Z'=R'+jX').
●
●
It can design matching circuits using LC, micro strip, electrical length line, and strip line.
●
It can design circuits with Γ, π, one line, two lines (stepped impedance type).
●
It can specify the complex number to port impedance.
【Example of design of Γ type matching circuit （micro strip）
】
●
●
This is an example of design so that a load of Z=100+j30［Ω］ will become Z=50［Ω］ via the matching circuit.
●
The matching circuit uses Γ type.
●
The short stub of the micro strip is used.
●
The graph shows that it is 50［Ω］ at 1.2GHz.
【Example of design using πtype matching circuit】
●
●
This is an example of an impedance design of 10 +j20［Ω］ seen from the matching circuit, to make a match of 50［Ω］ load.
●
The marker on the graph shows that Z=10+j20［Ω］ holds at 50MHz.
