Impedance matching techniques

[chihhao]

Does someone have document which is metioned about
impedance matching for advantage or disadvantage of
Pi , T-network and low pass,high pass structure.
Thanks a lot.

The T and pi choice is based on the cost and losses of the parts. Generally inductors are minimized because they cost more than capacitors and have higher losses. The high pass form usually has a wider bandwidth than the low pass form.

With the availability of low cost simulators, you can easily simulate all 4 combinations and pick the one that best meets your needs.

There is an old applicaton note from motorola at this address:

**broken link removed**

is the fifth item with the following title:

AN267 Application Note Matching Network Designs with Computer Solutions

It is quite useful for your needs.
