Failed UK Telecoms Merger Has Mixed Implications

Failed UK Telecoms Merger Has Mixed Implications for European Market - RF Cafe"While the European Commission's decision to block CK Hutchison's planned acquisition of Telefonica's British mobile operator O2 is credit negative for both Telefonica and CKHH's UK telecoms operations, its consequences will be mixed for Europe's telecoms sector, says Moody's Investors Service today in a new report. 'The failed deal will likely accelerate fixed-mobile consolidation in the UK with Telefonica looking for another buyer for O2. On the other hand, we expect ..."

1/3 of Cash is Owned by 5 U.S. Companies

1/3 of Cash is Owned by 5 U.S. Companies - RF Cafe"The rising cash holdings of U.S. corporations is increasingly in the hands of a few U.S. companies, with just 5 tech firms having grabbed 1/3 of it. Apple, Microsoft, Google, Cisco System and Oracle are sitting on $504B, or 30%, of the $1.7T in cash and cash equivalents held by U.S. non-financial companies in 2015, according to Moody's Investors Service ..." All these companies are headed by major supporters of a political party supposedly committed to ending this gross unbalance. You get what you vote for.

Where Are the Best Engineering Jobs in the U.S.?

Where Are the Best Engineering Jobs in the U.S.? - RF CafeEngineringJobs.com recently released a report titled "Where the Engineering Jobs Are: July 2015." The data is nearly a year old, but at least in this sluggish economy the situation does not change very rapidly, so it is likely still a good reflection of today's status. Rather than rank states by absolute number of engineering jobs, this system uses per capita engineering job number. Doing so attempts to normalize the result so that states with very large populations do not artificially dominate over states with small populations. Still, if you are looking for an engineering job, your best chance ...

Magnetostriction Devices and Filters for RF: Part 2

Magnetostriction Devices and Mechanical Filters for Radio Frequencies, July 1953 QST - RF CafeThis is Part II of a 3-part series of articles on magnetostriction devices. At audio and low IF frequencies, the use of ferrite elements to construct relatively high-Q resonant circuits for filtering was a big deal in the middle of the last century. Although not presented in this article, design formulas and tables were published to implement the familiar Butterworth, constant-k, Chebyshev, Gaussian, and other types. Tuning, particularly for higher order filters, could be a chore since it involved a cut--and-try method on the ferrite rods. However, that is what was available in the day, and it evidently worked well enough to be worth the trouble for desired ...
