    2020-4-22u2002·u2002To calculate the output voltage after the matching circuit, we need to know the ratio of impedance, in our case, 1500 Ω/75 Ω=20. The voltage ratio (like turns ratio in transformers) is equal to the square root of the impedance ratio, so √20≈8.7. This means that the output voltage will be 8.7 times bigger, so it will be equal to 8.7 mV.
