Anadigics says its HELP4 PAs reduce average current consumption by 30%, compared with previous generation PAs. They also have three mode states to achieve excellent power-added efficiencies at low-range and mid-range output power levels and have a quiescent current of less than 4 mA.
In a 3 mm by 3 mm footprint, the devices display very good linearity at maximum output power and feature internal voltage regulation. They also have an integrated “daisy chainable” directional RF coupler with 20dB directivity.
The V788D, N788, N910, and PF200 feature a 3.5- inch screen, 5 megapixel camera, and Android 2.3 Gingerbread operating system. The V889D has a 4-inch screen and Android 4.0 Ice Cream Sandwich operating system.
The ZTE V889D is powered by the AWT6621 and AWT6628A power amplifiers and the V788 is enabled by the AWT6621 power amplifier (PA).
ZTE’s N788 features Anadigics’ AWT6625A power amplifier. The N910 is powered by the AWT6624. and the PF200 is powered by the AWT6624.
“We look forward to working with ZTE as it continues to develop innovative smartphones for the global wireless market,” says Michael Canonico, senior vice president of worldwide sales at Anadigics.
“The strength of our product portfolio coupled with our Asia-centric strategy demonstrates Anadigics’ commitment to both product and service excellence. Our world-class applications centres in China further support Anadigics’ growth initiative.”
Anadigics’ HELP4 4G PAs use the Company’s proprietary InGaP-Plus technology to achieve optimal efficiency across low-range and mid- range output power levels and provide the lowest quiescent currents in the industry.
The AWT6621, AWT6624, AWT6625A, and AWT6628A power amplifiers are suited to WCMDA, HSPA and HSPA+ systems. They are designed to extend battery life in handsets, smart phones, tablets, netbooks, and notebooks.
Transmission in Asia speeds up with Infinera 500 Gb/s InP PICs
A trial showcasing long haul, high-bandwidth optical network transmission across 4,500 km of Pacnet’s C2C subsea network employs Infinera’s indium phosphide based PIC and FlexCoherent super- channels
Pacnet and Infinera have completed a joint effort demonstrating the successful transmission of more than 3 Tb/s of capacity over 4,500 km of Pacnet’s C2C network.
The testing was conducted with Infinera’s DTN-X platform, which has begun shipping this quarter and also demonstrated the ability to use FlexCoherent technology to software select the modulation format in order to optimise fibre capacity and reach.
Pacnet owns and operates the pan-Asian submarine cable network touching 21 cable landing stations and extends from India to the U.S. At the heart of this network is EAC-C2C, one of Asia’s largest fibre optic submarine cable networks, which spans 36,800 km and serves customers worldwide.
“We are impressed with Infinera’s DTN-X platform delivering 500 Gb/s FlexCoherent super-channels and integrated OTN switching without compromise,” says Bill Barney, Pacnet CEO.
“Pacnet is dedicated to offering our customers leading-edge communications services across the Pacific Rim. We accomplish this by collaborating
