Pi Filter Calculator (LPF): LC Low Pass Filter Design
Advertisement
This Pi filter calculator functions as an LC low pass filter, primarily used for impedance matching. It determines the appropriate inductance (L) and capacitance (C) values based on the input cutoff frequency (fc) and impedance (Z0).
Pi LPF Calculator
This is a simple calculator to help you design an LC-based Pi filter for low pass filtering applications.
Example:
- INPUTS: Fc = 900 MHz, Z0 = 50 Ohm
- OUTPUTS: L = 1.76 x 10-8 Henries, C = 7.077 x 10-12 farads
