The knowledge of microwave analysis is a very added advantage for any **Electronic Engineer** out there. It makes one better understand the networking system of a **two port **in relation to S parameter.

According to Wikipedia, the **S Parameters** describe the electrical behavior of linear electrical networks when undergoing various steady state stimuli by electrical signals.

Luckily, **Nickzom Calculator**, the calculator encyclopedia is happy to take care of all calculations dealing with S Parameter (Two Port Network) for you and also show you a step by step guide (workings) on how to solve this problem.

For the purpose of this post, I would show you how **Nickzom Calculator** solves for the following:

- Input and Output Reflection Coefficients
- Various Power Gains
- Mismatch Factors

First of all, you have to have access to this awesome software package.

One can access Nickzom Calculator+ (Professional Version) – **The Calculator Encyclopedia** via any of these channels:

Web – https://www.nickzom.org/calculator-plus

Android (Paid) – https://play.google.com/store/apps/details?id=org.nickzom.nickzomcalculator

Apple (Paid) – https://itunes.apple.com/us/app/nickzom-calculator/id1331162702?mt=8

Once you have got access to the software package, please proceed to the **Calculator Map** then scroll to **Engineering**

On clicking **Microwave Analysis,** you see

Click on the link **S Parameter | Two Port Network.**

Now, click on Input and Output Reflection Coefficients, the Various Power Gains and Mismatch Factors

You should know that the **S** in S Parameter stands for **Scattering** parameter

Since, we are dealing with a two port network, it would be a **Two by Two** matrix. At this stage, one is required to select the whether the value for the parameters are to be in **polar** coordinates or **rectangular** coordinates.

After making the required selections, click on **Calculate**

Now, enter the appropriate values

Lastly, simply click on Calculate for **Nickzom Calculator **to do what it does best, display the result with workings, and accurate solutions and formulas. In the case of this post, I will be displaying the result in the form of a video. Watch and Enjoy!

Easily, you get the answer for your computations in **Microwave Analysis** using Nickzom Calculator.

**Additional Knowledge** from Microwaves 101, tells us that there are **4** types of S parameters which are:

**Small signal S-parameters**are what we are talking about 99% of the time. By small signal, we mean that the signals have only linear effects on the network, small enough so that gain compression or other non-linear effects do not take place. For passive networks, small-signal is all you have to worry about, because they act linearly at any power level (at least until you blow them up).**Large signal S-parameters**are more complicated. In this case, the S-matrix will vary depending upon the input signal strength. Measuring and modeling large signal S-parameters will not be described on this page (perhaps we will get into that someday).**Mixed-mode S-parameters**refer to a special case of analyzing balanced circuits. We’re not going to get into that either!**Pulsed S-parameters**are measured on power devices so that an accurate representation is captured before the device heats up. This is a tricky measurement, and not something we’re gonna tackle yet.

Networks that can be described with S-parameters are usually single-frequency networks. **Receivers** and **mixers** aren’t referred to as having S-parameters, although you can certainly measure the reflection coefficients at each port and refer to these parameters as S-parameters. The trouble comes when one wishes to describe the frequency-conversion properties and this is not possible using S-parameters.
