i haven't been able to obtain a simple answer

S-parameters, also known as scattering parameters, are used to characterize the behavior of a microwave circuit. They describe how the circuit will respond to an applied input signal, and can be used to determine important performance metrics such as gain, reflection, and insertion loss.
S-parameters are typically measured using a vector network analyzer (VNA). The VNA sends a known input signal into the circuit and measures the reflected and transmitted signals at various frequencies. These measurements are then used to calculate the S-parameters.
S-parameters provide information about how a circuit will behave in terms of signal reflection, transmission, and attenuation. They can also be used to determine the impedance of the circuit and identify any mismatches or losses.
Yes, S-parameters are frequency-dependent. This means that their values can change at different frequencies, which is why they are typically measured over a range of frequencies to fully characterize a circuit's behavior.
S-parameters are related to other circuit parameters, such as impedance and admittance, through mathematical equations. They are also closely related to other parameters used in microwave circuits, such as reflection coefficient and transmission coefficient.
