The global wireless BTS infrastructure market revenues for the top OEMs grew by 3.7 percent for the third quarter of 2008 to $12.2 B compared with the third quarter of 2007, according to the latest report from EJL Wireless Research titled "Global Wireless OEM Financial Results Q3 2008." "The...

Mobile-TV is poised to become the next great mobile accessory, with analysts projecting that 50 million digital-TV-ready mobile handsets will ship in 2009. 1 For designers, making this task a reality is somewhat daunting, given the significant user-experience complexities that mobile-TV introduces, such as battery life, reception and range,...

The last two decades have witnessed the introduction of several new communication services that presented extraordinary challenges to microwave filter designers. Mobile communications cellular base stations and handsets require very tight electrical requirements to conserve precious frequency spectrum, miniaturization, large production volumes and low production cost. Filters for space...

Dual-mode circular resonator (DMCR)-based waveguide filters, introduced in the beginning of the 1970s, 1-6 have well known advantages, compared to traditional waveguide filters. DMCR-based filters allow for two orthogonal TE 111 modes to be employed by each circular cavity, thereby reducing by a factor of two the number of...

Starting from a small number of fabricated integrated inductors, and by means of accurate electromagnetic simulations and a physical-based inductor model, a new method to generate an integrated inductor library is reported in this article. The parametric model permits to find the geometric parameters of the inductor that provide...

Microwave filters are an essential component in modern wireless communication systems. It is important to reduce their size and weight in order to integrate them with other components in a single chip system. 1 Using a multilayer filter is the main trend in filter design, since it shows a...

It is not an easy task to predict the behaviour and future of regional and global markets at the best of times. So now, in the wake of the global financial crisis, when there is deep uncertainty and concern surrounding how far reaching the effects will be, such crystal...

Past Microwave Journal articles provide a fascinating look at the life and times of our industry and how we have weathered economic and social change. This fifth installment in our series recounts the 1990s, a decade that is still clearly visible in our recent memories. In the world at...

Developers of Software Defined Radio (SDR) waveforms are fortunate to have a myriad of high-performance technologies and targets available for waveform implementation in heterogeneous DSP and RF architectures. The challenge is how to co-design RF architectures together with baseband signal processing to create high performance and flexible SDR architectures...

Noise considerations are a key factor in the design of radio systems of all types and designers expend much effort in reducing system noise. Testing radio systems by inserting white Gaussian noise along with the signal has been a recognized test method for decades, but there are surprisingly few...
