Pi Filter calculator LPF | LC Low Pass Filter

This Pi filter calculator is used as LC low pass filter for impedance matching. It takes cutoff frequency (fc) and Z0 as input and calculates L (inductance) and C (capacitance) values.

Pi LPF calculator

Following is a simple LC based Pi filter calculator used for low pass filtering.

Example :
INPUTS : Fc =900 MHz, Z0 = 50 Ohm
OUTPUTS: L = 1.76 x 10^-8 Henries, C = 7.077 x 10^-12 farads
