More dielectric constants
Since these are so hard to find, I’m going to record all findings. According to a 1961 document called Plastic-Film-Dielectric…
More on transmission lines
PTFE has a more constant (!) dielectric constant over a reasonable frequency range (not that the 4 ohms delta of…
Transmission line calculation tool
Since the steps were too much, this excel file was created. In the spreadsheet, the green values can be entered,…
Twisted pair transmission line
For constructing transmission lines, coax is useful because it is available in 50 and 75 ohms. For transmission line transformers,…
