Muller, progenitor of the world's first 3D Smith
Chart software program, has teamed with a handful of able colleagues to release this commercial
version of this paradigm-changing design and analysis tool. 3D Smith Chart enables you to visualize
S-parameter data in ways not possible from the Flatland dweller's perspective that is the traditional
2D Smith chart. Flatland existed in a plane, and from an observer's perspective a 3-dimensional
object entering the plane from along the Z-axis seemed to appear out of nowhere ...
This back-page advertisement by
Model Rectifier Corporation (aka MRC) appeared in
the January 1972 issue of American Aircraft Modeler magazine. Note the cool collection of
[now] vintage test equipment shown in support of testing the R/C system.
The advertisement shows a rhombic antenna, the Dana 8015 RF frequency counter, Tektronix 7904 oscilloscope,
HP spectrum analyzer, RF communications synthesizer RF generator, Anritsu precision field strength meter.
I was 13 years old at the time, and anxiously watched for in the mailbox each month ...
RF Cafe visitor Tony C., who is an engineer working for on
of America's great, longtime manufacturers of green farm equipment, sent me a link to this unique memory
IC released by Signetics on April 1, 1973. Being April 1, 2017, it seems to be an appropriate day to
post the Signetics 25120 Fully Encoded, 9046 x N, Random access Write-Only Memory datasheet that per
Wikipedia, "...was created 'as a lark' by Signetics engineer John G 'Jack' Curtis and was inspired by
a fictitious and humorous vacuum tube datasheet from ..."

177,000 Coaxial Connector Adapter Combinations from CoaxSol
How many times have you dug through a drawer of
coaxial connector adapters and found what seemed
like every possible combination of TNCs, Ns, SMAs, TNCs, UHFs, SMBs, and <fill
in the blank>s except the one you really need? Sometimes the reason is simply because all
on hand are being used for something else and cannot be 'borrowed' for your use. Other times it is because
the need never existed before. Usually, a quick search on the Internet will turn up exactly want you
want, but for decent a quality adapter you will pay a stiff price - especially if it is a rare combination
of connector types. The truth is, not often is a combination like QMA-Male-Right-Angle-to-TNC-Female-Bulkhead
adapter or ...
EasyEDA® Online Schematic Capture & PCB Layout
as the paperless office, predicted to quickly become a reality when personal computers were beginning
to dominate the workplace and home in the 1980s, has yet to occur, neither has desktop software for
high-end applications totally replaced online equivalents. Microsoft has made good progress in the last
few years in moving part of their Office suite online, you still need a local copy of Visio, Project,
and even their Visual Studio software development tools if you want to use them. Graphics and video
editing software cannot be used efficiently online. The problem is mostly due to time latency between
user input and software display response. Speed on the host server end is addressable with pumped up
computing power and extra ...
