L Matching Network

Computes the inductance (L), capacitance (C), and Q factor for an L-network impedance matcher. Automatically selects the correct LP or HP topology based on source vs load resistance and DC current mode.

Inputs

Frequency

Operating frequency value

Frequency Unit Multiplier

Unit multiplier — Hz: 1, KHz: 1000, MHz: 1000000, GHz: 1000000000

Source Resistance(Ω)

Source resistance in ohms

Source Reactance(Ω)

Source reactance in ohms (can be negative for capacitive)

Load Resistance(Ω)

Load resistance in ohms

Load Reactance(Ω)

Load reactance in ohms (can be negative for capacitive)

DC Current Mode (1 = Pass DC, 0 = Block DC)

1 = Pass DC current (LP topology), 0 = Block DC current (HP topology)

Results

⚠Frequency must be greater than zero

Inductance—HRequired inductor value in henries

Capacitance—FRequired capacitor value in farads

Q Factor—Circuit Q factor
