MIMO techniques are becoming a popular combination with OFDM radio formats because they offer the possibility of increased spectral efficiency. The first commercially available MIMO system was in WLAN, but the interest has spread to cellular formats including WiMAX and LTE. Each format has adopted slightly different techniques and...

As leading developers of the mobile WiMAX standard, EB and Nokia Siemens Networks have agreed to co-operate on the further development of WiMAX technology. According to the agreement, EB will sell its WiMAX baseband software asset to Nokia Siemens Networks. The parties have agreed to continue the WiMAX baseband...

Panasonic Corp. and Renesas Technology Corp. have announced their collaboration to develop elemental process technologies for System-on-Chips (SoC) of the next-generation 32 nm node. The two companies are confident that their 32 nm node transistor technology and other advances can soon be applied to products in mass production. It...

Link Microtek 's Engineering Division has invested in a 200 W TWT amplifier system that enables the company to carry out broadband high-power testing of its comprehensive range of waveguide components and subsystems. Having such a facility in-house is unusual among microwave component manufacturers, but it means the company...

Worldmax , a competitive WiMAX operator in the Netherlands, is utilizing Ceragon Networks’ FibeAir® IP solutions in one of Europe’s first commercial WiMAX networks. With this deployment Worldmax joins more than 40 WiMAX operators and service providers worldwide who are using Ceragon’s solutions for high-capacity backhaul applications. The solution...

Reference...

GPS semiconductor vendors are increasingly focusing on GSM handsets as their next target market for GPS chipsets. While until now CDMA handsets and navigation devices have been the main GPS product categories, GSM mobile phones are expected to increasingly feature GPS-chipsets as handset-based navigation and a wide range of...

The research foundations for MiG , in the field of fast EM CAD and optimization methods for satellite and wireless communication components, were laid over 30 years ago with the development of fast mode-matching CAD procedures for waveguide discontinuities and filters. Twenty seven years ago (1981) at the 11...

Founded in 1997 in the Anhui Province of China, BL Microwave is a private, high-technology enterprise specializing in the design and manufacture of microwave filters and other microwave components. In particular, the company produces low-pass, high-pass, band-pass and band-reject filters as well as LC, cavity, ceramic, waveguide, tubular, helical...

High-frequency technology didn’t earn its reputation as black magic for no reason. Unlike low-frequency circuits, microwave circuits don’t behave in a totally predictable way, so “tweaking” has been an accepted mainstay of the microwave design approach/fl ow. Fortunately, high-frequency design tools have dramatically improved so that tweaking of prototype...
