Oracle to Acquire Sun Microsystems

April 20, 2009
Back in the mid-80s, do you remember sign-up sheets for workstations, which were extremely expensive and in short supply. Design software such as MDS (HP), Libra (EEsof) and Harmonica (Compact Software) required the high performance computing only available on these machines and EM simulation software such as HFSS was not yet widely available. Many of us (junior) engineers had to work later in the evening waiting for a workstation to became available. Do you remember the Unix wars between the proponents of BSD from Univerity of California, Berkeley and System V from AT&T? BSD Unix vendor Sun Microsytems and AT&T...

R&S Demos Femtocell Design Verification

March 31, 2009
At CTIA Wireless 2009, Rohde & Schwarz is demonstrating their LTE frequency division duplexing (FDD) testing capabilities based on the newest femtocell design from mimoOn. The compact test setup features the R&S® SMBV100A vector signal generator and the R&S® FSV signal analyzer to generate and analyze LTE signals that meet the newest specification. The test setup on display at Rohde & Schwarz booth 6033 verifies that the femtocell reference design from mimoOn correctly operates according to the LTE specification that is about to be finalized. Accurate validation of the generated downlink signal of the mimoOn reference design is carried out...

Greenray Industries Debuts New TCXO

March 25, 2009
Greenray Industries of Mechanicsburg, PA announced a new High Frequency TCXO for Wireless & Mobile Apps last month, the T121 TCXO just in time for Satellite 2009. The device is designed to serve as a super-stable frequency reference in high shock and high vibration environments. The T121 Series TCXO, available from 50 to 100MHz, provides extremely stable sinewave output and temperature stability to ±0.5ppm over -40 to +85°C. The T121 measures 0.68 x 0.68 x 0.200” and features vibration sensitivity of 7 x 10-10/g or better. The T121 Series combines a compact, rugged package, tight stability and high frequency availability...

CPI Satcom Showcases 100 watt Ku-band outdoor SSPA

March 25, 2009
CPI Satcom Division is featuring its 100 watt Ku-band outdoor SSPA at the SATELLITE 2009 Conference and Exhibition. This outdoor SSPA is the latest addition to the company’s extensive range of solid state amplifiers and is being touted by the company for its flexibility and easy maintainance. Frequency bands can be changed among X-, C- and Ku-band very quickly without rewiring and using only minor hand tools. Swapping out fans typically takes less time than it does to simply remove the cover on competing products. The ease of owning a CPI SSPA is enhanced by the company’s fifteen worldwide service...

Treating Tumors with Microwave Ablation

March 11, 2009
More news from the "microwaves in applied science" front. A new minimally-invasive option for treating liver tumors, called microwave ablation, is now available at UC San Diego Medical Center and Moores UCSD Cancer Center, the only hospitals in the region to offer this technology to patients. “Microwave ablation causes the tumor to be quickly and precisely removed. If necessary, multiple tumors can be treated at the same time,” said Marquis Hart, MD, transplant surgeon at UC San Diego Medical Center. “This method appears to be more efficient than other ablation techniques which translates to better tumor destruction and less time...

ADS 2009 Targets HF/HS Co-Design

March 6, 2009
Agilent has just recently announced the release of ADS 2009, targeting the high-frequency & high speed front end co-design (IC/Package/Board) challenges discussed in February's MWJ lead story - "The Dawn of Nano-scale Technology". The complexity of these designs require tight integration between the the front-end (simulation & verification) and back-end (Cadence or Mentor Graphics)tools. For example, 4G LTE phones must also have Bluetooth, Wifi and MIMO capabilities which means multi-antennas operating over multi-frequency bands while remaining backward compatible with 3G and 2G modes. In turn, high frequency and high speed components will need to fit into smaller volumes and closer...
