The 80,000 fans expected per match at the legendary Maracanã Stadium in Rio de Janeiro during the 2014 FIFA World Cup will be able to share the experience with family and friends over a new multi-operator, multi-technology network infrastructure enabled by Radio Frequency Systems (RFS), the global wireless and broadcast infrastructure specialist.

High Speed Interconnects, a custom, high-performance, coaxial cable extruder and manufacturer, has released a new video that demonstrates their achievement of capacitance as low as 8 picofarads (pF) per foot. When compared to other competitor coaxial cables built with various dielectrics typically achieving not less than 16 pF per foot, HSI’s cable uses a proprietary ePTFE dielectric called VP90. The enhanced dielectric achieves near air dielectric performance, eliciting an extremely low dielectric constant and thus, low capacitance and low loss.

RFMW, Ltd. announces design and sales support for a wideband GaAs VPIN limiter capable of protecting sensitive components against high power incident signals. The TriQuint TGL2205-SM operates from 2 to 6 GHz with low insertion loss of less than 0.6 dB. It can limit up to 100 W incident pulsed-power with a low flat leakage of less than 16.5 dBm. The TGL2205-SM die has a protective surface passivation layer that provides enhanced environmental robustness. The TGL2205-SM does not require DC bias and is available in a 4 x 4 mm QFN package allowing simple integration with minimal impact to system performance. TriQuint's TGL2205-SM is well suited for both commercial and defense related applications.

San-tron, Inc., a manufacturer of RF coaxial connectors and cable assemblies, reviewed several new innovative connectors and assemblies at the International Microwave Symposium in Tampa, Fla., June 3-6, 2014. Chief among are two small but robust connectors. First is their new pSeries pressurized connectors which provide low-loss, high-stability performance through 30 GHz at +/-65 psi. These pressurized connectors, which meet the IP68 standard, feature a simplified, three-piece design – body, center contact, and an innovative dielectric – which eliminates troublesome internal O-rings, gaskets, and silicone greases.

Analog Devices, Inc. introduced new highly integrated RF ICs that greatly simplify the design and reduce the development cost of multi-band base stations and point-to-point (PtP) radios. These new devices include the ADRF6720 I/Q modulator, ADRF6820 I/Q demodulator and ADRF6612 dual-mixer. The highly integrated devices enable the design of base station and high-performance radios requiring multi-band support, high dynamic range and wide channel bandwidths. These products are ideal for designs for 3G/4G communication, microwave PtP radios, military/aerospace and instrumentation applications. ADI’s new RF ICs offer the same performance as radio designs based on a combination of discrete solutions, yet in a significantly smaller form factor. The new devices feature an embedded low phase noise synthesizer, RF switch and balun, digital step attenuator (DSA) and programmable linearity optimization.

Analog Devices and Hittite Microwave Corporation today announced that the two companies have entered into a definitive agreement whereby ADI will acquire Hittite for $78 per share in cash. The closing price of Hittite’s common stock on June 6, 2014 was $60.56 per share.

Taiwan's FarEasTone Telecommunications has become the first mobile operator to launch a commercial LTE service on the APT700 band, based on technologies provided by Ericsson.

RFMW Ltdhas acquired Axomic Pte Ltd, a specialized RF & microwave component supplier for Southeast Asian customers.
