Network Q vs Source Impedance
L-Network Impedance Matching
Q = sqrt(R_high/R_low - 1)
X_series = Q x R_low
X_shunt = R_high / Q
Choose series inductor + shunt capacitor, or vice versa, to realize the reactance values at the operating frequency.
Example Calculation
Match 50 ohms to 200 ohms at 100 MHz.
- 01Q = sqrt(200/50 - 1) = sqrt(3) = 1.732
- 02X_series = 1.732 x 50 = 86.6 ohms
- 03X_shunt = 200 / 1.732 = 115.5 ohms
