Software without installation, without java, without java script, without Windows drivers, incompatible VBasic dll, outdated *.net libraries, #.net libraries, buggy C++ bs, suddenly expired forever licences, "blue screen of Microsoft death", and endless administrative (/IT) tasks. Screw ever changing java, incompatible versions of JS, or mutually incompatible OS versions. Embedded is the way to go. Electronic Smith Chart

- A step to technology independence that succeeded -
We can only dream about Fortran double matissa length. Some compilers are not compliant with the C standard.
Do you think people deserve at least one working OS, going through purgatory from DOS2.1, Win3.11, NT4.0, Win25?
Electronic Smith Chart PowerSmith©™ /simulator/s-parameters/noise figure/..
PowerSmith is RF simulation program. Use of the program is for analysis and matching of discrete circuits, lumped and distributed elements, transmission lines, stubs, baluns, antennas, amplifiers, receivers, transmitters, or FPGAs.

Control question
You have 1kW and the SWR=1.44; How much power do you burn?
The load is 34.8 ohms or 72 ohms real.
32.5 Watts is the heat. That's not the whole story.
Any load impedance mismatch change the shape of output signal, harmonics, intermodulations.
You are not able to pull out full power. Where the power goes?
The power bounces back from the load. Overloading power amplifier by bounced voltage, and extreme current.
Resulting in excessive heat and thermal (symptom) current run-away. Keep low SWR.
Decreasing temperature of active device by 10C degrees increases life span of the active device by about
102.5= 316x. (Arrhenius 1859 - 1927, activation energy).
Questions and Answers
Q: I am Nanook. I was 30 years in project management, manager, and heard the buzzword "Smith Chart". Now we do FPGA (other people do) and it doesn't work. The system has signal reflections and crosstalk. The chip is very hot burning Amps. What should we do?
A: The FPGA needs signal matching and signal integrity. Mistakes cause signal reflection, signal shape distortion, crosstalk, amplitude distortion, and interference. The FPGA won't work properly. Call for help.
Q: We have heat problem. I noticed when I put my finger in specific spot on the RF Power device, the signal jumps up and down, and the current drops. The power supply is buzzing. What is it?
A: Calculate the impedance, measure the impedance with vector network analyzer, measure SWR. There might be additional problem. Do you need help? We do consulting.
Q: When I physically move the 2.4GHz and 5GHz antenna, the signal quality rapidly changes. We used propagation simulation program. Everything looks great. But the throughput is misery. What is it, what can I do?
A: It can be multiple things at once. It might be a good idea to pick up the phone, and call. Default use of full TX power is a mistake. Stronger doesn't mean better. Call.
Q: Looking at the datasheet of Dual-Gate MOSFET BF981 from Vishay-Telefunken, and J310. The point of minimum noise figure and noise circles are of my interest. The common gate s-parameters are missing. What can I do with it? Convert it?
A: The BF981 datasheet noise numbers seems to be right. The best idea is to measure the noise figure. At the university they may have noise figure meter. The measured noise figure with noise resistance can be loaded to PowerSmith.
Q: I have cascaded two types of LNAs with close minimum Noise Factor and two different gains. How can I decide which one is better for the first position? Please, provide notes.
A: There is an algorithm to calculate noise quality number. It will tell, what to use for the first position.
However, it does not tell anything about IP3. Neglecting IP3 may lead to system anomalies. Call
Q: I get Windows 11 blue screen of computer death.!! Microsoft decided to reinstall the whole crippled OS system without notification. All my work is gone. Two years of work are lost. Shit. What can I do?
A: This is Bill Gates' Microsoft. What you can do? Return your MS_Windows OS. Charge them. Request $$$ for lost time and lost work. Same situation arise when your hard drive dies.
The OS System
Try VMware for multiple OS platforms. It can switch over to different OS within seconds. If it would be so fantastic, everybody would use it. Point of interest may be the gentoo Linux, Ubuntu Linux, Lynx, Fedora Linux, Slackware Linux, PCLinuxOS, LinuxMint, worth to mention minix3. It will take time for Windows to reinvent UNIX. Stable evolving system is an OPEN OS with accessible source code, where everybody can contribute and debug.
For the PowerSmith users
We have tried to do something for small companies and hobbyist.
The non-profit users are encouraged to use the software. The profit-oriented entities are encouraged to support further development. The software was written during winter 2000 in Winterpeg Manitoba (-40C outside, -40F, with windshield -52C). Global warming is for nuts. During the next arctic winter, a graphical user interface was added. There are over 42,000 lines. Several thousands of hours were invested. There is no component limit. The favorite commercial "five-component-limit" was not implemented. Use whatever number of components you want. Memory is the limit.
A significant number of people were interested in copying the source code for commercial activities, and porting to C++ Microsoft crap. The "C" language is fully documented to the registry level. That is why you have Linux running. The ISS Space station use Linux. C++ is not fully documented to the registry level.
PowerSmith runs on Win95, Win98, Win2000, Windows XP, Win7, FAT32, and later versions. The NTFS file system is not supported. DOSbox can be downloaded in seconds.
The treasure throve is in math and calculus. No fake LTSpice simulation models.
The graphics is an interface between the numbers and the user.
How it works
You can download without license keys, without extracting your own private information, without suddenly expired licenses, without tracking, without violation of your privacy, without flooding your email with useless spam, without hidden fees. Everything depends on you.
Now - you are the investor.

Well before 2006 started "The Technology Theft Campaign" in Canada and USA with the trademark "Copied in China 2025".
Canadian and US companies were full of "Chinese traders". Many people have not understood. They were expecting Chinese investments. That never happened. The hidden instructions and target were different. There was naivety and missing experience how to handle this. Do people take brain with them?
Basic mistake was in estimation of human behavior. Wishful expectations based on wrong social behaviour model. Wrong. Completely wrong. The target was MIMICs, microwaves, SiGe, GaAs, HBT, memories, processors, IBM, HP, Agilent, Broadcom, silicon foundries, and software companies. You name it. The naivety and greed moved most of US R&D to China and India. America first?
This was an eye opener. Too late. Wrong direction. You know the rest.
Today, you can ask -"Are you secretly working for the Chines?" And you can point with finger.
Today our company still use proprietary software gadgets.
- With PowerSmith, we gained a step to independence -
