Unknown Frequency Quiz

Unknown Frequency Quiz, September 1965 Popular Electronics - RF CafeLots of old-time sci-fi movies and TV shows liked to display Lissajous patterns on oscilloscopes when an authentic high tech look was needed in a scene. Every engineer, technician, and physicist in the world - me included - roll his or her eyes at the sight of such a lame attempt to impress the public. Of course the truth is the first time I saw a Lissajous pattern gyrating on an o-scope screen, I was mesmerized. The need to crank on the signal generator knobs and take control of the electroluminescent object d'art was overwhelming. Now, in the same manner that watching the first couple Space Shuttle launches was a thrill not to be missed and then became just another launch, so, too, is watching a live Lissajous pattern on a scope - it's just another Lissajous. Except, well, that's not quite so - at least for me. I always eagerly viewed Shuttle launches ...

Rotating Subreflector Produces Circular Scanning

Rotating Subreflector Produces Circular Scanning, February 14, 1964 Electronics Magazine - RF CafeElectronically steered phased arrays have largely replaced mechanically steered antennas in the last couple decades. In an effort to eliminate the need for a waveguide rotary joint, which is both expensive and complex when built for high reliability under harsh operating conditions, Japanese engineers developed an alternative where a small subreflector is orbited about a central axis to produce a small scanning angle. The measured half power bandwidth of the central beam was about 7.5°, while the half power scan width about the main axis boresight appears per one of the plots to be around 30° or so (if I interpret it correctly). I assume this scheme was never pursued much beyond the experimental phase ...

New Rules to Govern CB Radio

New Rules to Govern CB, October 1964 Popular Electronics - RF CafeCitizens' Band (CB) radio began in 1945, just after World War II, in order to provide common folks with a means of both fixed and mobile radio communications that required only paying a fee to operate. Amateur radio (Ham radio) did and still does require that the operator pass a written test to gain transmitting privileges (anyone may receive a signal). CB was and is used for both fixed base and mobile communications. Evidently, by 1964 there was enough use and misuse of the airwaves that the Federal Communications Commission (FCC) found it necessary to publish and enforce a new set of rules for users. CB radio began operations in the 460-470 MHz UHF band, then moved to 27 MHz in 1958 since equipment could be manufactured in a manner more affordable to a wider segment of the public ...

MMIC Die Testing Made Easy with Ultra-Wideband 0 dB Attenuator Dice

MMIC Die Testing Made Easy with Ultra-Wideband 0 dB Attenuator Dice - RF CafeHere is a very useful concept for providing accessible test point in RF and microwave circuits - a 0 dB attenuator to insert between stages for easy probing to a controlled impedance interface. "MMIC Die Testing Made Easy with Ultra-Wideband 0 dB Attenuator (Thru-line) Dice," by Radha Setty of Mini-Circuits, appears in Microwave Digest magazine. Sez Radha, "Microwave hybrid circuitry is generally built by integrating several discrete dice via wire bonding. Circuit designers are faced with the task of predicting the performance of hybrids, which comes with some specific challenges. Most RF/microwave MMIC dice are built with 'ground-signal-ground' bonding pads at each of the RF ports to correspond with the terminals of a die probe and allow accurate extraction of S-parameters ..."

Comics: Ye Antique Radio Collector

Comics: Ye Antique Radio Collector, October 1964 Popular Electronics - RF CafeHere for your almost-Friday enjoyment is a collection of radio-themed comics from a 1964 issue of Popular Electronics magazine. The scenario in the first comic is one that an owner of an antiques store told me happens often with cunning customers. Now that eBay has been around for so long, shop owners, yard/garage sale holders, Craigslist sellers, and even places like Goodwill know what their items are really worth and price accordingly. In fact, about the only things you can find at those venues anymore is utter junk or stuff too big to sell and ship on eBay - like an area rug or a night stand. Every once in a while you'll come across a good deal when the person is not Internet savvy, but not often. We hardly even look anymore ...

Hong Kong Adds Quality Electronics to Its Bargain Basement Line

Hong Kong Adds Quality Electronics to Its Bargain Basement Line, December 13, 1965 Electronics Magazine - RF CafePardon my gallows humor, but when I first saw this photo from a 1965 issue of Electronics magazine of this manufacturing plant being built in Hong Kong, my thought was that maybe those scaffolds in front of the windows were actually there to prevent despondent, hopeless employees from jumping onto the sidewalks below. These days, more stylish and socially acceptable nets are used. The take-away from this story is that while it might seem the shifting of manufacturing to and/or sourcing of foreign-made products by U.S. firms from China is not a recent phenomenon. This was half a century ago before the fall of the Berlin Wall, before the breakup of the U.S.S.R., the mowing down of student protestors in Tiananmen Square, and other high profile ...

Electronics Newsletter c.1965 - Satellite Radio & TV

Electronics Newsletter, December 13, 1965 Electronics Magazine - RF CafeAlthough less than a decade had passed since NASA launched its first satellite (Explorer 1), planners there were already dreaming of the day when direct satellite-to-home and satellite-to-car signals would be broadcast on a commercial basis. This 1965 issue of Electronics magazine notes an intention to begin with FM radio station airing akin to what we know today as satellite radio. Then, by 1977 the country would be treated to satellite-to-home television programming powered by a space-borne SNAP-8 (Space Nuclear Auxiliary Power) generator. Sirius XM Radio made its debut in 2001, while home satellite TV service began in 1976. Also mentioned is the USSR's fourth failed attempt to safely land an instrument package (Luna 8, aka Lunik 8) on the Moon ...

JFET's - Put Last Month's Theory to Work

JFET's - Put Last Month's Theory to Work, June 1969 Radio-Electronics - RF CafeThe introduction of field-effect transistors (FET's) into the electronics world was a major benefit to designers needing lower power consumption and perhaps more importantly, high input impedances for active circuits. The two most fundamentally distinct type of FET's are the metal-oxide-semiconductor field-effect transistor (MOSFET) and the junction field-effect transistor (JFET). Both FET types are voltage-controlled devices and do not require a bias current (hence the high input impedance) like a bipolar junction transistor (BJT) does. Neither FET type has a PN junction. A JFET uses a high resistance semiconductor channel region between the source and drain with an ohmic contact to the gate, whereas the MOSFET has a insulative oxide layer ...
