Anatech Electronics, a manufacturer of RF and microwave filters, has published its March newsletter. As always, it includes both company news and some tidbits about relevant industry happenings. In it, Sam Benzacar discusses, among other topics, spectrum sharing, including the ISM bands and a DARPA program called Shared Spectrum Access for Radar and Communications (SSPARC) that has the goal of developing more advanced sharing technology so that radars and military and commercial communications systems can cooperate in near real time. Anatech's business is to make certain that system and circuit designers have capable filters available to assure successful implementation.

A Word from Sam Benzacar

Anatech Electronics Newsletter for March 2017 (Sam Benzacar) - RF CafeBy Sam Benzacar

When it comes to spectrum, no one likes to share, but as we can't make any more of it, that's one of the very few alternatives. Generally, two services share the same frequencies and one has priority over the other. When the second-tier service detects activity on the same or sometimes an adjacent channel, it must move elsewhere. While this sounds like a great way to encourage frequency reuse, it has been widely debated for years as various companies complained that it would be too complex, impossible to enforce, or cause other headaches. But one fact is a near certainty: there will be interference.

Spectrum sharing isn't a new concept, as it's used by various services in the crowded ISM band at 2450 MHz and is a mandatory requirement for using the "TV white spaces" opened up after over-the-air TV broadcasting transitioned from analog to digital transmission techniques. It's also part of the national public safety broadband network, for which there should soon be a contract award.

The Department of Defense saw this coming years ago and is taking steps to make sure "intruders" don't interfere with its radars through various initiatives. One of is a DARPA program called Shared Spectrum Access for Radar and Communications (SSPARC) that has the goal of developing more advanced sharing technology so that radars and military and commercial communications systems can cooperate in near real time. There are others as well.

Over time, these initiatives should make spectrum sharing must less likely to cause interference. In the meantime, it seems inevitable that sharing frequencies will cause interference problems for both the primary and secondary services. One of the reasons is that unless communications are able, as DARPA proposes, to react almost instantaneously there will be times when both are transmitting (and attempting to receive) at the same time. I may be overly pessimistic on this subject but three decades in the filter business has taught me that interference has a way of defeating the best efforts of approaches in which multiple systems operate close together. I hope I'm wrong, but….

If you're designing any type of communication system that operates close to other services with narrow (or no) guard bands, are working to build a new system destined to operate in a shared environment, or are having interference problems with a fielded system, please give Anatech Electronics a call. We've been solving interference problems with high-performance RF and microwave filters since 1990. You can reach us at (973) 772-4242 or by email at sales@anatechelectronics.com.

What's News

DoD Explores Human Cell RF Interaction - RF CafeDoD Explores Human Cell RF Interaction

DARPA wants to know more about how human cells use electromagnetic radiation to talk to each other, and is investigating it in a program called RadioBio. The goal is to determine if cells can exchange information with EM signals, what the cells are communicating, and how they achieve it. The program will attempt to learn how natural "antennas" are capable of generating and receiving information in a noisy, cluttered EM environment," at frequencies from kHz to THz.


Mesh Network for Weather Alerts Needs No Internet Access - RF CafeMesh Network for Weather Alerts Needs No Internet Access

Scientists are building networking technology to provide people weather alerts even if they don't have internet connectivity. Developed by IBM Research and The Weather Company, Mesh Network Alerts is a peer-to-peer mesh networking technology that allows Android devices to communicate with each other without the need for Wi-Fi or cellular connectivity. It will first be deployed in India before expanding to Africa, Asia, and Latin America where networks are congested and connectivity is limited. The accompanying smartphone app requires only 3.2 Mbyte/s of storage and can store weather data offline for up to 24 hr.


Mesh Network for Weather Alerts Needs No Internet Access - RF CafeGaN Plays Well in Space

Belgian chip research consortium Imec and satellite payload developer Thales Alenia Space have demonstrated that Imec's GaN-on-Si power devices based can withstand heavy ion and neutron irradiation with no degradation in performance, making them well suited for spaceflight applications. Imec irradiated its GaN power devices with heavy ions of xenon and neutrons that are the primary cause of failed electronic circuits in satellites.



IAI Develops Forest-Penetrating Radar - RF CafeIAI Develops Forest-Penetrating Radar

Israel Aerospace Industries (IAI) has developed a radar that can identify targets traveling through heavily wooded areas. The ELM-2112FP persistent surveillance foliage penetration radar is being marketed as a border security solution. The radar's forest-penetrating abilities rely on the ability of FMCW modulation to track people and vehicles in congested areas even without a clear line-of-sight.

About RF Cafe

Kirt Blattenberger - RF Cafe Webmaster

Copyright: 1996 - 2024


    Kirt Blattenberger,


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...
