The Opportunities and Challenges of LTE Unlicensed in 5 GHz
David Witkowski, Executive Director, Wireless Communications Initiative
In 1998, the Federal Communications Commission established the Unlicensed National Information Infrastructure or U-NII 5 GHz bands. These are used primarily for Wi-Fi networks in homes, offices, hotels, airports, and other public spaces and also consumer devices. U-NII is also used by wireless Internet Service Providers, linking public safety radio sites, and for monitoring and critical infrastructure such as gas/oil pipelines.

The Multidimensional Alan Borck
By Charles Alan Borck, Founder, RLC Electronics

Fred Ortiz, President, dB Control

Charles Alan Borck, founder of RLC Electronics in Mt. Kisco, NY, died on March 1 at 87.

No one who ever did business with Alan Borck would ever consider him indecisive or indirect. While he was a man of few words, they were always what he believed to be the truth, like them or not. Alan was a stand-up guy, and a very bright one as well.

While the veterans of the RF and microwave industry may remember Alan as a hard-nosed businessman, no one is one-dimensional; certainly not Alan Borck, who valued family, hard work, accomplishment, honesty, loyalty and respect for others. He was born in 1925 to Charlie and Lillian Borck, and grew up in New Rochelle, NY, running cross-country at New Rochelle High School, one of many sports at which Alan would ultimately become proficient, from skiing to tennis. After graduating a semester early, his mother said this was no time to sit back and relax — he was going to college.

He found one (Renssellear Polytechnic Institute) that would allow him to begin in January rather than the usual September. He graduated from RPI in 1947 in two and half years and went to work at ITT in Nutley, NJ, with several other engineers who later founded RF and microwave companies. He kept a strong involvement with RPI, which was important to him. In 1997, he was the recipient of the Thomas W. Phelan Fellows Award that honors alumni or friends of the institute who by their professional or other achievements and service to the institute set an example for Rensselaer students to emulate.

Shortly after graduating from RPI, he met Virginia Herson, the love of his life and the woman who would remain his wife for 62 years and with whom he traveled the world. Shortly after their marriage, Alan left ITT and commuted weekly to Amsterdam, NY, where he worked for Empire Devices, some of whose products are collectors’ items today. He initially lived with the company’s owners, Joe Lorch and Mike Hargas, who founded the company in 1946. Joe went on to found Lorch Microwave (now part of Smith Industries). In 1959, with three kids in tow, the entrepreneurial bug bit Alan and he founded RLC Electronics, in which he participated until his death. There are precious few RF and microwave companies around today that after 50 years are still named, owned, or operated by their founders, a testament to the company and the man who built and grew it.

Alan was the quintessential family man, a product of the ‘50s, the era of Father Knows Best, to which his son Doug and daughters Leslie and Jackie can attest. They knew him for his “tough love” that extended to his employees as well: tough at the core, but loving and caring on the inside. To his employees, he was respected, admired and appreciated; He was joined at RLC by son Doug in 1978 and grandson Jeffrey in 2011. To his family, he was a simple man who lived by a simple creed: be the best that you can be — in business, the golf course (where he tirelessly worked to improve his game), at the card table playing bridge, or at the backyard pool hanging out with friends and family. He attended his kids’ every sporting event, concert, and theatrical performance and never missed a family meal or holiday.

Alan Borck’s legacy is the family he raised with Virginia and the service to the RF and microwave industry through the establishment of a strong, vibrant company in RLC Electronics, Inc. Alan will be remembered by his friends and family, and his legacy will be carried on by his three children, seven grandchildren and 50 employees at RLC.

Uncertain Times for DefenseWill OpenRFM Shake Up the Microwave Industry?
By Barry Manz

Throughout the history of the RF and microwave industry there has never been a form factor standardizing the electromechanical, software, control plane, and thermal interfaces used by integrated microwave assemblies (IMAs) employed in defense systems. Rather, every system has been built to meet the requirements of a specific system, which may be but probably isn’t compatible with any other system. It’s simply the way the industry has always responded to requests from subcontractors that in turn must meet the physical, electrical, and RF requirements of prime contractors. Read More...
