PI-NETWORK MATCHING

The sketch below shows a Pi-Network match between R1 to R2.

                 PI-Network Matching

               Calculate a network to match between two resistive loads,
                 R1 and R2.

               R1,R2,Q,F(MHz) [<Enter>=Quit] ? _

Note: R1 > R2 Units: ohms, MHz

You should choose R1, R2, and Q such that:

Let's design a network to match a 100 ohm load to a 50 ohm source at 150 MHz with the quality factor Q=4. Input data as "100,50,4,150" and press <Enter>.

Here is the output calculation for the Pi-Network impedance match network:

                C1 = 4.2441E-11 F    (42.441 pF)
                C2 = 5.8115E-11 F    (58.115 pF)
                L = 4.2058E-08 H      (42.058 nH)
