Anatech Electronics July 2023 Newsletter

Anatech Electronics July 2023 Newsletter - RF CafeSam Benzacar of Anatech Electronics, an RF and microwave filter company, has published his July 2023 newsletter that features his short op−ed entitled "Another Annoyance for Radio Astronomers." In it, Sam discusses a subject I have highlighted a few times, which is the interference issues being caused by the massive satellite constellations being deployed around the Earth. Between Starlink (SpaceX) and Project Kuiper (Amazon), Guo Wang (China), and Europe planning one of its own, as many as 100,000 satellites ultimately (maybe more, with >4,000 already deployed), many in low Earth orbit (LEO), could be blocking radio frequency, infrared, visible light, ultraviolet, and x-ray information from cleanly reaching terrestrial astronomy telescopes. Ingenuous solutions to mitigating scintillation effects of the atmosphere have been devised, but no similar method can be used for satellite interference. Sam's write-up has to do specifically with the newly discovered RFI being created from the satellites themselves - it appears in bands specifically reserved for radio astronomy. As you know, uncorrelated inband interference is very difficult to mitigate...

Anatech Electronics June 2023 Newsletter

Anatech Electronics June 2023 Newsletter - RF CafeSam Benzacar of Anatech Electronics, an RF and microwave filter company, has published his May 2023 newsletter that features his short op−ed entitled "Filters Save the Day." In it, Sam discusses how two of the biggest issues of the day concerning RF interference - the coexistence of C-band cellphone service and radar altimeters, and AM radio in electric vehicles - are relatively easily solved with filters. I have posted links to many news stories covering both challenges in the last few years. Sam makes a good point about the AM radio in EV's, that being whereas car manufacturers say the noise generated by the propulsion systems (brushless motors which run on high frequency pulses) will wreak havoc with AM radio, there will certainly be other susceptibilities needing to be dealt with by onboard systems. I will add that dense urban environments filled with EMI-spewing EV's might also cause serious problems for external systems as the ambient noise floor rises ever higher...

Axiom: Scopes Get Second Look w/Integrated Analyzers

Axiom Blog: Scopes Get a Second Look with Integrated Analyzers - RF CafeAxiom Test Equipment, an electronic test equipment rental and sales company has published a new blog post that covers how high-speed oscilloscopes with on-board spectrum analysis capability can be a more efficient testing approach. Traditionally, testing in the time and frequency domains meant separate signal paths and separate units. An oscilloscope shows signals in the time domain while a spectrum analyzer shows signals in the frequency domain. However, a more efficient approach - and a less crowded test bench - can be achieved using a high-speed oscilloscope with on-board spectrum analysis capability. That way, it is possible to have multiple looks at a signal of interest with a single unit. Specifying a combination oscilloscope/spectrum analyzer requires defining performance ranges for the two units, so that each will deliver the capabilities needed for a targeted set of test applications. For an oscilloscope, this typically includes the number of measurement channels, bandwidth per channel, sample rate, vertical bit resolution, trigger level range, time base range, noise floor, and acceptable jitter. For a spectrum analyzer, it is number of channels, frequency range, acquisition bandwidth range, frequency resolution...

Anatech Electronics May 2023 Newsletter

Anatech Electronics May 2023 Newsletter - RF CafeSam Benzacar of Anatech Electronics, an RF and microwave filter company, has published his May 2023 newsletter that features his short op−ed entitled "Z-Axis Positioning Finally Arrives," which discusses the FCC's "Wireless E911 Location Accuracy Requirements" mandate for providing altitude information from the point an emergency assistance call is placed. It says in part, "...requires nationwide wireless providers to deploy z-axis technology nationwide by April 3, 2025." It is not a trivial requirement since cell tower triangulation and even embedded GPS sensors cannot provide altitude (z-axis) position precisely enough to pinpoint floor-level location. The FCC wants to know what floor of a building from which the call originates. Sam mentions NextNav's Pinnacle system that uses a precision barometric pressure sensor in the phone, tablet, computer, etc., to provide the altitude information. After reviewing available info on Pinnacle, I don't see how a pressure sensor can provide floor-level height without a very nearby reference pressure sensor at some fixed, known height to compare readings. Ambient barometric pressure is constantly changing, so a referenceless reading is practically useless. Pilots always calibrate their altimeters (barometers calibrated to read out in units of height) at a point on the airport where the altitude is know...

IPP RF Feedback Resistors for Solid State Amplifiers

Innovative Power Products RF Feedback Resistors for Solid State Amplifiers - RF CafeInnovative Power Products (IPP), with more than 30 years of experience designing & manufacturing RF & microwave passive components, introduces a line of RF Feedback Resistors for Solid-State Amplifiers. IPP's line of Feedback Resistors are designed to support wideband RF/Microwave solid-state transistor power amplifiers, which require resistive feedback. Using negative resistive feedback is a simple way to improve transistor amplifier stability and frequency gain sloping. These feedback resistors are flange mounted and designed to fit directly over the RF/microwave transistor using the same mounting holes as the transistor. This mounting configuration utilizes normally unused space above the transistor without taking up valuable PCB area adjacent to the transistor. This also decreases parasitic inductance associated with resistor leads...

Anatech Electronics April 2023 Newsletter

Anatech Electronics April 2023 Newsletter - RF CafeSam Benzacar of Anatech Electronics, an RF and microwave filter company, has published his April 2023 newsletter that features his short op−ed entitled "Havana Syndrome: Case Closed," which discusses where the U.S. government recently declared their investigation into the mysterious neurological issues some foreign embassy staff had been reporting showed that use of a microwave emitter to induce maladies was "very unlikely." Keep in mind that conclusion was brought to you by the same type government jackbooted thugs who brought you "safe and effective" vaccines. Sam, as do I, believes just because government investigators have declared the "conspiracy theories" to be unfounded, it does not remove the possibility of radiation poisoning given the history of Communist regimes in not so long ago events. Russia and other countries were caught zapping personnel with microwaves on multiple occasions. Sam wrote about the Havana Syndrome back in 2019...

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
