The reality of cellular network evolution is that infrastructure roll out precedes that of the handset user equipment. But without user equipment (UE), how do you test a base station? Since 1999, the answer for 3GPP networks has been the Aeroflex TM500 Test Mobile. Used by every major infrastructure...

Agilent Technologies Inc. announced a fully coded bit error ratio (BER) solution for the time division duplex (TDD) version of 3GPP’s long-term evolution (LTE) standard using 2x2 and 4x4 multiple input/multiple output (MIMO) technology. This solution complements Agilent’s same capability for the frequency division duplexing (FDD) version of LTE...

While microwave and millimeter-wave high-power vacuum electron devices (VED) remain “below the radar” of many industry observers, the total available market (TAM) for this segment is nearly $1 B. Despite its size, and although these tubes (valves) remain essential elements in specialized military, scientific/medical and space communications applications, this...

The future success of the semiconductor industry will depend on how successful it is in implementing 3D IC technology to meet the demands of a 17-year-old consumer named Jeremy, according to Ziptronix CEO Dan Donabedian. In a presentation at the fifth annual 3D Architectures for Semiconductor Integration and Packaging...

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...
