Anritsu ME7873NR Facilitates 5G mmWave UE Rollout

Anritsu ME7873NR Facilitates 5G mmWave UE Rollout - RF CafeAnritsu Company has developed the new Compact Antenna Test Range (CATR) Anechoic Chamber 2 MA8172B configuration for its New Radio RF Conformance Test System ME7873NR to support 5G millimetre wave (mmWave) 2 Angle of Arrival (2 AoA) Radio Resource Management (RRM) tests. Anritsu’s MA8172B solution is unique in industry as it is based on hybrid of IFF (Indirect Far Field) and DFF (Direct Far Field) test methodologies and this really helps customer save real estate space. A solution based on all DFF or IFF will be bulky and expensive. Anritsu helps in providing value to customer by making this new solution lower cost, smaller footprint, upgradable, and serve multiple test areas. Evaluating UE communications quality and connection stability during handovers between base stations is a difficult technical challenge for mmWave mobile communications. Consequently, Anritsu has developed its MA8172B upgrade model for the Over-the-Air (OTA) CATR...

Anatech Electronics December Newsletter

Anatech Electronics December 2022 Newsletter - RF CafeSam Benzacar of Anatech Electronics, an RF and microwave filter company, has published his December 2022 newsletter that features his short op−ed entitled "The Resurgence of Microwave Directed Energy Weapons." The premise of directed energy (DE) weapons is to blast RF/microwave energy at a specific frequency or band of frequencies at a high enough power to confuse or totally disable drones and/or missiles while in flight, before reaching their intended targets. Sam argues reasonably that the relatively low power and aiming requirements of a microwave directed energy system can be much more effective than a high power laser beam that must be aimed and track the target precisely enough to make surface contact. An RF system can make multiple "shots" in the same time required for a laser power supply to recharge between shots. A great example of how DE works can be seen in this decade-old video of an Active Denial System use to disperse unruly crowds. The targets are humans, but the reactions are analogous to how radio receivers are affected...

CMT: Near & Far Field Measurement

Copper Mountain Technologies: Near & Far Field Measurement - RF CafeCopper Mountain Technologies (CMT) has a whitepaper available entitled, "Near and Far Field Measurement." It begins, "To obtain optimal performance in an over the air RF system, the antennas must be chosen to meet specific requirements. Performance parameters such as size, wind-loading, environmental ruggedness, transmission pattern, bandwidth, and power handling capability should be considered. Especially important in an RF system design is the 'link budget.' This parameter determines the end-to-end RF loss and is affected by transmitter output power, feedline loss, transmit antenna gain, path loss through the air, receiver antenna gain, feedline loss once again and receiver noise-figure among other factors. A failure to meet the link budget in an RF system design will result in noisy performance and loss of coverage. In this application note, methods of measuring the transmission (or reception) pattern which determines antenna gain with a VNA will be examined. Most antennas possess some directionality to their performance..."

During this webinar, we will review the possible pitfalls during de-embedding and measurement of a DUT on a fixture...

Anatech Electronics November 2022 Newsletter

Anatech Electronics November 2022 Newsletter - RF CafeSam Benzacar of Anatech Electronics, an RF and microwave filter company, has published his November 2022 newsletter that features his short op−ed entitled "Face Reality: Level 5 Vehicle Autonomy Won't Be Here Anytime Soon." A definition of Level 5 on the level5auto.com website declares thus: "Level 5 driving is full driving automation. That is, the car's systems can accomplish every part of the dynamic driving task (DDT). They can also monitor all of the vehicle's surroundings and make predictions about what the objects in the space around it will do next. Further, the car can do this anywhere. The systems are no longer confined to a limited operational design domain (ODD). And, finally, the car operates without the expectation or need for a human to ever take over driving - even in the case of a system failure." The scheme requires not only perfect AI (artificial intelligence), but perfectly functioning electronics processors, sensors, and control over the car's throttle, steering, and brakes. That's a pretty tall order. As Sam notes, if any monitoring and/or intervention by the human occupant is required, then Level 5 has not been achieved. Level 5 may well be an asymptote of the vehicle autonomy curve...

Weighing the Benefits of Benchtop vs. USB Based TE

Weighing the Benefits of Benchtop vs. USB Based Test Equipment - RF CafeAxiom Test Equipment, Inc., an electronic test equipment rental and sales company has published a new blog post entitled "Weighing the Benefits of Benchtop vs. USB Based Test Equipment," that explains the differences between benchtop and USB based test equipment to identify the best option for a user's project. The most glaring difference between USB-controlled units and standard benchtop units is usually size. A USB unit fits next to a laptop computer on a small desk while a benchtop unit occupies the better part of a laboratory work area or 6U or more of a standard 19-in.-wide test equipment rack. Another difference between a USB unit and a traditional benchtop unit is the computer. For USB equipment, the computer is part of the test setup, whereas for a benchtop unit, it is an option...

Anatech Electronics October 2022 Newsletter

Anatech Electronics October 2022 Newsletter - RF CafeSam Benzacar of Anatech Electronics, an RF and microwave filter company, has published his October 2022 newsletter that features his short op−ed entitled "It's Getting Crowded in Low Earth Orbit," where he discusses the rapidly increasing number of both operational and non-operational satellites in low earth orbit (LEO). It presents both a physical space crowding problem and an RF spectrum crowding problem. Companies like Anatech help with the RF crowding by designing and building filters to mitigate the presence of nearby signals. Companies like ClearSpace SA (Switzerland) are working the physical space crowding issue by designing and building grappling bot satellites which will grab a satellite (or large debris) and drag it to a lower orbit for atmospheric re-entry. I wonder what the carbon footprint is of a launch vehicle needed to get the bot aloft...

ALCOR is a 5G low-profile surface mount antenna that has been developed to be compact but still cover bands from 617-6000 MHz. It has a small footprint of 40 x 10 x 1.6 (mm) and a fallback to 4G/3G/2G. ATRIA is even more compact but still covers bands from 698-2690 MHz (also falls back to 3G/2G). It measures only 30.0 x 7.0 x 1.6 (mm) and requires a small clearance area (don't be fooled by claims of small antennas which often need a much bigger clearance area)...

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...
