Paratek Expands and Improves ParaScan(TM) RF Tuning Material.Revolutionary Material Enables Smaller, More Reliable Wireless Devices NASHUA, N.H. -- Paratek, a leading technology innovator of radio frequency (RF) components for mobile wireless applications, announces significant performance improvements made to its ParaScan[TM] RF tuning material. ParaScan is based on a proprietary doped version of Barium Strontium Titanate Strontium titanate is an oxide of strontium and titanium with the chemical formula SrTiO3. It is a centrosymmetric ferroelectric material with a perovskite structure. (BST (convention) BST - British Summer Time. The name for daylight-saving time in the UK GMT time zone. ) and forms the baseline technology for an entirely new class of electronically tunable integrated capacitor circuits from Paratek. These tunable ICs enable wireless devices to be smaller, operate more reliably, and deliver high-bandwidth, data-rich services. A fundamental advantage of the ParaScan material is that it provides low-loss tuning of circuit impedances or frequencies, which will allow next-generation wireless products to perform better and more efficiently. Paratek Chief Product Officer Dr. Jim Oakes commented further on ParaScan: "By adding dopants to BST, ParaScan reduces leakage currents by more than an order of magnitude A change in quantity or volume as measured by the decimal point. For example, from tens to hundreds is one order of magnitude. Tens to thousands is two orders of magnitude; tens to millions is three orders of magnitude, etc. and significantly decreases the RF losses in the material. These advantages will allow our next-generation tunable wireless products to replace conventional, fixed-frequency RF circuits and provide high reliability, low insertion loss The amount of loss attributed to a particular device being used in (inserted into) the system. For example, a circuit added to filter out unwanted frequencies may reduce the output current by some amount. See injection loss. , and wide tuning ranges." The capacitive networks produced from ParaScan can be arranged in an almost limitless number of ways to meet the advanced RF tuning needs demanded by these applications. Using ParaScan as a foundational technology, Paratek is presently making highly tunable and highly miniaturized RF circuits for next-generation mobile phones and mobile radios. The material is ready for large-scale use now, and high-volume manufacturing is underway with a strategic partner. Outperforms Varactors, MEMS (MicroElectroMechanical Systems) Tiny mechanical devices that are built onto semiconductor chips and are measured in micrometers. In the research labs since the 1980s, MEMS devices began to materialize as commercial products in the mid-1990s. & GaAs ParaScan offers dramatic performance improvements over pure BST within the wireless frequency spectrum. Along with Q values
Q values are the difference of energies of the parent nuclides to the daughter nuclides. as high as 150 at 1 GHz and 80 at 2 GHz the integrated capacitor circuits demonstrate leakage currents of less than 100 nA and greatly improved reliability. ParaScan also offers high-power handling, high capacitance density, IP3 of greater than 70 dBm, and fast switching speed. Compared with other tunable technologies such as varactors, MEMS, PIN diodes, and GaAs, ParaScan exhibits an excellent combination of performance characteristics with respect to high Q, power handling, linearity, insertion loss, continuous broadband tuning range, fast response time, and size.
