A Stellar Partnership

Those of you following me on twitter (@mwjournal) received a tweet yesterday as I was about to meet with the folks at Stellar Industries in Millbury Massachusetts –a quiet New England town blending residential homes and “old-school manufacturing” facilities on the outskirts of Worcester.

The company does a brisk business selling products to the Telecom, Biomedical, and Defense Industries. The company believes there is a good business opportunity for their products in the RF market, thus they requested...

Industry Hardware Gets 15 Minutes of Fame

I get that this is entertainment and not real news, so please indulge my little rant, which is meant for your entertainment. My "exposure" to the daily television show GMA (Good Morning America) occurs as a captive viewer stuck on a treadmill at the local gym. With no access to the TV controls, getting in shape usually means turning a little piece of my brain into mush on those days. Between the steady diet of "mind-numbing repetition of that day's big story with little depth or insight" or the "day after day reporting of nothing new in some long-drawn...

Uplink and Downlink to Follow Two Different Technology Directions

A new report released today by Mobile Experts predicts an industry shift away from the 3GPP roadmap, which calls for evolution to 8x8 MIMO (Multiple Input-Multiple Output) technology. “Field testing has shown limited benefit from the simple addition of more antennas and early implementation of Multi-User MIMO” said Joe Madden, Principal Analyst at Mobile Experts. “Instead of blindly following the 3GPP evolution path, mobile operators are looking for different, creative ways to boost throughput and capacity. Interference cancellation and Cooperative Multipoint (CoMP), as well as advanced MU-MIMO will be important technologies during the next few years”. “Mobile Experts is...

Comparing Active and Passive Mixers with Besser Associates

In a recent webinar, one of the attendees commented that Besser Instructor Allen Podell was presenting results based on "rather wimpy performance assumptions" for his active mixer versus passive mixer comparison (see below) and suggested using newer active mixers such as ADL5801 or LT5557 from ADI or LTC? This attendee asserted that mixers based on these particular devices compete very well with the best passive mixers­. Allen took up this challenge and did a little investigation. His response is below. Post-webinar response from Allen Podell - First of all, I must admit that it is true that the ADL5801 and...
