Paratek

Electronically tunable RF circuitry for multi-function, multi-frequency wireless devices

Founded in 1998, Paratek develops tunable solutions for wireless communications applications. The Company’s products comprise a revolutionary new class of electronically tunable radio frequency (RF) components used in mobile phones and government radio systems. These include Adaptive Impedance Matching Modules (AIMM), RF filters, pre-selectors, phase shifters, and other advanced RF circuits. The foundation for these components is ParaScan™, a patented voltage-tunable dielectric materials technology (described further in the Technology Summary). Using this advanced material, Paratek produces ‘tunable integrated circuits’ that comprise custom networks of voltage-tunable capacitors. Used in RF front-end applications, these highly miniaturized circuits have the ability to continuously tune from 30 MHz to 5 GHz and bring to reality ‘frequency-agility’ in software-defined, multi-function radios.

For wireless handset applications, Paratek has produced a remark­able product called AIMM. These ‘Adaptive Impedance Matching Modules’ instantly sense and correct for impedance mismatches that can degrade the performance of wireless handsets. New genera­tions of mobile phones will benefit greatly from AIMM, because the closed-loop system optimizes the overall performance of the phone…including the antenna circuitry, the power amplifier, and the battery. Next-generation multi-band mobile phones will be smaller, lighter, and have a broad array of features and functions. As a self-contained component, AIMM is particularly suited for these new devices because it allows designers a wide degree of latitude in meeting increasingly stringent performance objectives without increasing antenna size.

Paratek is headquartered in Columbia, Maryland. In-Q-Tel initially invested in Paratek in June, 2004. For more information about Paratek, please visit www.paratek.com.
