Network Type Comparison
| Network | Components | Best For | Q Control |
|---|---|---|---|
| L-Network | 2 (L + C) | Simple matching, wide bandwidth | Fixed by Z ratio |
| Pi Network | 3 (C-L-C) | Low-pass filtering, harmonic rejection | Adjustable |
| T Network | 3 (L-C-L) | High-pass filtering | Adjustable |
| λ/4 Line | 1 (TL) | Real impedances, microwave | Fixed |
L-networks are simplest but have fixed Q. Pi and T networks offer Q control for bandwidth tuning. Quarter-wave transformers are ideal for microwave and purely resistive impedances.
