AWR KK , a division of AWR Corp., an innovation leader in high-frequency EDA, announced an invitation to designers in Japan to take the AXIEM Challenge beginning today through July 15, 2010. AWR's AXIEM EM simulator is the most accurate solver in its class and can typically solve large...

In 2010, only about 40,000 4G machine-to-machine (M2M) cellular modules will ship. All will be WiMAX-based. In contrast, ABI Research estimates that in 2015, more than 12.6 million of the devices – including LTE-compatible models – will ship worldwide. Why would M2M communication, which usually involves relatively low data-rates,...

Integral Systems Inc. announced that its wholly-owned subsidiary, RT Logic , has more than doubled the bandwidth of its real-time T400CS Channel Simulator from 40 to 85 MHz. The T400CS Channel Simulator generates precise and realistic signals for research and development (R&D) and test activities on communications equipment for...

Skyworks Solutions Inc. has introduced five 3 x 3 mm power amplifier modules (PAM) with an integrated daisy chain coupler for next-generation platforms. These PAMs support all required modulations for a given frequency band including CDMA, WCDMA and LTE handsets and datacards. In addition, they enable a variety of...

The requirements for higher and higher data rates and the saturation of existing frequencies and networks are pushing applications higher and higher in frequency. This is true for both the "traditional" frequency bands around 38 GHz, but also at frequencies higher than 40 GHz. This movement has been consolidated...

In recent years, advances within two fields have had a major impact on how filters are designed today. One is the advent of powerful electromagnetic (EM) software, which provides results that are close to measurements. However, analysis and optimization of complete filters is often too resource and time consuming...

Blogging: My first experience at blogging came with an invitation from editor David Vye to contribute a guest blog on the Microwave Journal website. It was like a jump into the deep end of the pool! I had never blogged prior and certainly not imagined such a prominent place...

Welcome to the April edition of The WaveGuide . Here in New England, the sun is shining, the flowers are blooming and spring is in the air. The Boston Marathon is around the corner and the baseball season marathon has just begun. The MTT-S IMS is rapidly approaching and...

Few people have more IMS exhibition experience than Microwave Journal ’s Marketing and Event Coordinator, Kristen Anderson (nee Dednah). Kristen helped manage the exhibition for over a decade. Think the logistics for your booth are complicated? Try multiplying those challenges by the total number of IMS exhibitors, year-in and...
