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 typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

WiMAX: A Fading Star?

As an article in The Wall Street Journal points out, the VHS-versus-Betamax war may be a good analogy (in some respects) for WiMAX versus LTE, which the latter is winning hands down. The article points out a good analysis of the subject on the TechRadar website, stating that  that Intel (the original champion of WiMAX) has changed its tune. There are currently 20 million WiMaX subscribers throughout the world and in some places it may survive – but probably not in a meaningful way in the U.S.

LightSquared Decision This Month?

LightSquared says it believes the FCC will allow it to become the first wholesale provider of LTE services in the U.S. when it makes it decision sometime this month, according toLightSquared's executive vice president, Martin Harriman at the Mobile Future Forward conference in Seattle, according to FierceWireless. Sprint has already lined up journalists and analysts to hear its 4G roadmap on October 7, and in July LightSquared gave Sprint the option to purchase its wholesale LTE network. A week later Sprint's WiMAX provider, Clearwire, declared plans to build an LTE-advanced network if it can get the money. This would leapfrog LTE and couldn't be deployed until after LTE-Advanced becomes a standard. If the FCC gives LightSquared the green light, Sprint could be launching LightSquared's LTE network as early as next year. Regardless, LightSquared still faces the core issue of interference to GPS, which seems almost insurmountable.

Dead Satellite to Fall Soon

A functionally dead satellite will fall back to Earth during the last week of September, according to NASA. The spacecraft, an old NASA climate probe called the Upper Atmosphere Research Satellite (UARS), was decommissioned in 2005 and has since been slowly losing altitude. The 6 1/2-ton satellite will make a final uncontrolled plunge through Earth's atmosphere. The Department of Defense is one of the organizations monitoring it.Pieces of it could land from south of Juneau, Alaska to just north of the tip of South America. NASA estimates a 1-in-3,200 chance a satellite part could hit someone. Most of it will burn up after entering Earth's atmosphere. You can track the spacecraft's demise here.

The Key Role of Multiband Combiners and Band Separators

I've written a lot in this column about interference and for good reason: it's a bigger issue now then ever for commercial and public safety wireless systems -- and is getting worse. However, wireless carriers also face the continuing challenge of reducing costs wherever possible, from the device level straight through to the antenna. Multiband combiners and separators and bandpass combiners are invaluable components that not only reduce costs but reduce system complexity as well.   These versatile products allow the transmit and receive signals from several wireless bands to be multiplexed into a single antenna, eliminating a variety of components and helping to reduce the growing rat's nest of cables within single-carrier or co-located sites. These bands can be either within a single wireless frequency allocation, such as 700 MHz, or different bands, for example GSM and PCS, including both uplink and downlink frequencies for each network. As their core components are cavity filters, they retain the superb performance of this filter type, including extremely high rejection and isolation along with the ability to handle very high output power levels.   Anatech has been designing and manufacturing bandpass combiners and separators for more than 20 years have met the most challenging requirements. In addition to standard products available at AMCrf.com, we can quickly build custom designs to handle any wireless band from VHF through microwave frequencies, as well as weatherproofing for outdoor installations and other special requirements.

If you'd like to learn more about these capabilities, please give us a call at (973) 772-4242 or send us an e-mail to sales@anatechelectronics.com..

MILCOM 2011 logo

With its list of exhibitors and attendees growing every year, it's more and more important to attend MILCOM so you can stay on top of trends from the component through system and program levels. This year, we'll be offering a greater range of information and activities at our booth than ever before, including demonstrations that show our products “in action”, so visitors can visualize their performance and especially see how they solve interference problems in the field. So please come visit us at Booth 800.
