Austin, Tex.—Freescale Semiconductor entered the gallium arsenide
(GaAs) Monolithic Microwave Integrated Circuit (MMIC) sector with
the launch of four devices aimed at macro base stations, repeaters
and femtocells employed in wireless networks. The devices address
low-noise amplifiers and transmit power amplifiers— two elements of
wireless infrastructure equipment for which extremely high RF
performance is critical. The devices are also designed for low
power consumption, resulting in o...
Seeking to gain more traction for its silicon-on-sapphire
technology in RF designs, Peregrine Semiconductor Corp. has formed
an exclusive joint development and foundry agreement with IBM Corp.
Fast-growing Peregrine (San Diego)--which is looking to file an
initial public offering (IPO) in the next 12-to-15 months--has also
altered its foundry strategy as part of the major announcement.
Prior to the announcement, Peregrine’s foundry partners included
MagnaChip, Oki/Rohm, Sapphicon and UMC...
Rumors are running rampant again that IBM Corp. is looking to sell
its chip unit. For years, the rumors have been on and off that IBM
wants to sell its Microelectronics unit. Some say GlobalFoundries
Inc. is a possible suitor. Others say IBM Micro is too expensive
and not worth the trouble. ''Who wants IBM Micro? Nobody,’’ says
one analyst.
近日，在微电子所领导和四室领导的大力支持下，四室金智研究员领导的毫米波器件与电路组研制成功一款基于InP
HBT的W波段压控振荡器(VCO)。该VCO采用电流镜偏置和两级差分结构，其中第一级为振荡源核心，第二级为输出缓冲级，利用BC结电容作为调谐元件，电路面积为0.65mm*0.75mm，芯片照片如图1所示。经测试，振荡器调谐频率范围为75GHz-85GHz，其中80GHz以上频段单端输出功率高于0dBm，相位噪声低于-80dBc/Hz@10MHz
offset，图2为该VCO的频谱输出照片。 
M/A-Com Technology Solutions Inc. (Lowell, Mass.), a supplier of
semiconductors, components, and subassemblies for use in RF,
microwave and millimeter-wave applications, has acquired Mimix
Broadband Inc. Mimix will become part of the M/A-COM Tech family of
companies. Mimix is a fabless supplier of high performance gallium
arsenide (GaAs) semiconductors. The transaction is subject to
customary closing conditions and is currently expected to close in
late May 2010. Financial terms were not ...
BASF has created an advanced copper plating chemistry for current
and future generation chip technologies. The innovative chemical
solution, which is the direct result of the joint development
program with IBM started in June 2007, outperforms other
commercially available chemistries. The two companies are extending
their cooperation on setting the parameters for mass production.
The related technology, chemicals and materials are expected to be
commercialized in mid 2010. “We are very e...
Agilent Technologies launched the Infiniium 90000 X-Series
oscilloscope family with industry-leading, real-time bandwidth of
32GHz. Ten new models range from 16 GHz to 32 GHz and are bandwidth
upgradable. These new scopes deliver the lowest noise and have the
lowest jitter measurement floor in the industry, ensuring superior
measurement accuracy. The accompanying probing system offers
browsing to 30 GHz with a full range of accessories rated to 28 GHz
and the ability to upgrade bandwidth ...
You know Avago, right? They're the company that grew out of HP's
component division. The history behind the company is fairly
interesting. HP developed instrumentation, printers, etc. They
needed the enabling components and technology for these devices and
in most cases, the components that were available were not up to
the standards required by HP. Hence, they built it themselves.
Before long, this group was selling these components to others, and
thus, a division was formed, eventually ...
