Royal Philips Electronics has announced that the conversion to the Restriction of Hazardous Substances (RoHS) compliant/lead-free semiconductor products has been completed well ahead of European legislation mandating the manufacture of such electronic products by 1 July 2006 under European Commission Directive 2002/95/EC. In July 2001, Philips Semiconductors teamed up...

UK-based RFI Global Services , an independent provider of specialist testing and approval services to the cellular industry worldwide, continues to expand its range of test capabilities by taking delivery of the 19th test platform from Rohde & Schwarz . This is the first step in the company's aggressive...

AVX Corp. is now offering the LP0603 harmonic low pass filter with lead-free land grid array (LGA) termination. The ITF LGA low pass filter is based on thin-film technology and provides a miniature part with excellent high frequency performance and rugged construction for reliable automatic assembly. The ITF low...

Advanced Ku-band radar systems used in airborne military platforms need reliable, small size and weight, high power amplifiers. Sophia Wireless Inc. has developed a solid-state power amplifier, model MPC8-1520, which meets these requirements. Its key features include: Operating frequency: 16 to 17 GHz Internally pulsed RF DC storage capacitor...

A new product family of low noise amplifiers (LNA) has been introduced that is specifically designed to increase a wireless system’s performance and reliability. The Super LNA Series LNAs are optimized to meet the design goal of achieving the lowest noise figure and best return loss simultaneously over a...

The microwave industry is tied to the birth of radar. Figure 1 is a whimsical look at the birth of radar as portrayed in a 1960s ad for Bomac tubes. In reality, radar was developed primarily at the MIT Radiation Laboratory (RadLab) during World War II. Much of the...

Coplanar waveguides are widely used in MMICs as interconnects and matching networks. Designing low loss, multifunctional and highly integrable transmission lines is a key factor in obtaining high performance from MMICs in silicon technology. 1 Nevertheless, the low resistivity of a standard silicon substrate deteriorates the performance of on-chip...

The investigation of the use of ultra-wideband (UWB) has been one of the most controversial technologies of modern times. Its applications can be seen in diverse areas such as local area networks, position location searching, advanced imaging of the human body, etc. Microwave ring resonators are the components proposed...

Integration of RF power, RF small signal, digital, DC and supervision circuits is still one of the main goals of modern radar, satellite and wireless communications technology. Today’s solutions of close-to-antenna devices use a stack approach for integration of RF filters with power splitters/combiners and multilayer printed circuit boards...

Thermal resistance is a measure of the amount by which the junction temperature rises for a given level of power dissipation in a transistor Thermal resistance is important since it determines how much power a device and package combination can safely dissipate. Thermal resistance measurements normally require the measurement...
