Module corrects handset RF imbalances
A revolutionary matching module aims to improve RF performance of next-generation mobile handsets.
Paratek has developed a revolutionary product that will improve RF performance of next-generation mobile handsets The Adaptive Impedance Matching Module (AIMM) will give mobile phones the ability to adapt for changing real-world conditions that degrade handset performance

Compact and fast dual gigabit Ethernet
Advantech, industrial computer manufacturer and automation innovator, releases its PICMG-3.1-compliant PCI Mezzanine Card (PMC), the MIC-3665.
AIMM, designed for rapid insertion into wireless handheld units, is based on Paratek's ParaScan RF tuning material and the recently introduced ParaTune family of passive tunable ICs.
The AIMM was specifically designed to address some of the most challenging and difficult problems facing handset makers, carriers and users.
How the phone is held, how it is stored, distance from the basestation, and changing from flip-open to flip-closed can all lead to "detuned" and less-efficient handsets.

Wall mountable node solution has high capacity
Advantech has launched the IPC-7220 industrial computer chassis, the next-generation wall-mountable industrial node solution with high capacity for ATX motherboards.
The industry sees this in the form of dropped or missed calls, marginal coverage, and poor battery performance because current fixed circuits are unable to adapt and retune to compensate.
The "self-correcting" feature of the AIMM gives mobile handsets the ability to work at an optimum level regardless of environmental conditions.
The AIMM is a fully integrated multichip module that monitors and corrects for impedance mismatches in all types of mobile devices.
Sensors within the AIMM monitor impedance mismatches as they occur and instantly correct for them, creating a closed-loop automatic process.
Changes in temperature, unit-to-unit handset variation, voltage differences, and multiprotocol (GSM, Edge, WCDMA) operation can also lead to mismatches.
The "adaptive" feature of the AIMM yields several important advantages, according to Greg Mendolia, Senior Vice President Mobile Wireless Products for Paratek.
"With AIMM in their handsets, users will see a significant increase in call quality plus a major decrease in dropped and missed calls under all conditions".
"Carriers will be able to increase their call-start success rate and introduce newer revenue-generating, high-bandwidth services".
"Handset makers will be able to provide better performance from smaller antennas, including an increase in total radiated power (TRP), longer battery life and dramatically improved link margin".
The AIMM will also shorten development cycles and time to market for new handsets, giving manufacturers the ability to quickly respond to changing market trends with performance-optimised products.
"AIMM is the right solution at the right time and we can produce it now", concluded Mendolia.
The AIMM is designed for high volume, cost-effective production using standard processes and techniques.
Concept prototypes of AIMM are available now.
