measurement of SiGe stacks for sub 45 nm technology nodes.
Isaac Mazor, CEO and president of Jordan Valley Semiconductors, said: “SiGe metrology has traditionally been very slow with only a few measurements per hour, which limits fab productivity. The new JVX7200 tool addresses the challenge, solving this process bottleneck with more than an order-of-magnitude throughput improvement, thereby reducing response time to crises.”
The JVX7200 tool leapfrogs contemporary in- line SiGe metrologies and combines a fast 2D HRXRD detector for composition and relaxation measurements with an ultra-small spot, fast XRR detector. The tool is compatible with fully automated modern fabs, and features both a small carbon footprint and a low cost of ownership.
Anadigics New HELP4 PAs Aid Booming 3G Mobile Device Market
The latest family of WCDMA Power Amplifiers (PAs) offer a 50% reduction in current consumption and up to 75% longer battery life.
Anadigics is marketing several new single-band power amplifiers designed for use in 3G mobile devices running on the WCDMA standard. The firm’s HELP (High-Efficiency-at-Low-Power) line of power amplifiers are ideal for a wide range of mobile device applications as they deliver maximum efficiency at various power levels, including a 50% reduction in current consumption where mobile devices operate most frequently. They are also claimed to enable up to 75% longer battery life, resulting in significantly longer talk time in handsets.
AWT6625and AWT6628 products, each designed for specific wireless bands. As the 3G smartphone market continues to grow, and with the emergence of 4G mobile technology, the new HELP4 power amplifiers meet customer demands for efficiency, flexibility, performance and reliability in their mobile devices.
All the devices in the AWT66xx series are now ramping into volume production; complete evaluation kits are available upon request.
“Even with the emergence of 4G mobile technology today, we continue to see a tremendous opportunity in WCDMA as the 3G smartphone market continues to expand at an astounding pace,” said Marcus Wise, VP, Wireless RF Products at Anadigics.
“We have realized tremendous success in the global marketplace with our broad portfolio of 3G products that cover every major standard. We are also paving the way to 4G with a strong portfolio of our forthcoming LTE and WiMAX products. Our HELP4 products deliver the efficiency, flexibility, performance and reliability our customers demand to differentiate and deliver the technologically advanced solutions that consumers expect from their mobile devices,” he concluded.
With the proliferation of technologies like HSPA+, which improve wireless network performance, the global 3G WCDMA market remains the most pervasive 3G system globally. According to the GSA (Global mobile Suppliers Association), 3G/WCDMA is the leading 3G system globally with commercial service in 135 countries. Ninety-seven percent of WCDMA operators have commercially launched HSPA. Yet mobile broadband downlink and uplink speeds using HSPA are evolving. The Network Update reports on 80 operator commitments to deploy HSPA+ including 41 commercial systems launched in 26 countries.
The AWT6621, AWT6622, AWT6624, AWT6625 and AWT6628 each include high-performance directional couplers in a 3 x 3 x 1 (mm) footprint. Each device is HSPA and HSPA+ compliant for the highest data levels and offers three mode states to achieve high power-added efficiencies at several power levels during the phone operation. These products also enable low quiescent current and low leakage current in shutdown mode.
Anadigics’ fourth generation of HELP PAs (HELP4) family features the AWT6621, AWT6622, AWT6624,
