Linearizer Technology, Inc. (LTI) specializes in the solution of problems involving the non-linearity of RF/microwave components and systems. LTI provides both manufacturing and consulting services. LTI’s principal business is the production of linearizers for high power microwave amplifiers.
Linearizer Technology. Inc (LTI) does not make amplifiers: it makes amplifiers better by reducing their distortion. LTI accomplishes this by producing modules that correct an amplifier's distortion. These modules are called Linearizers.
These modules are called Linearizers. They are placed in front of the amplifier. The function performed by the linearizer in relation to the amplifier is very similar to that of eyeglasses in relation to the eye. The eye distorts the image seen: the glasses pre-distort the image. When these two distortions are combined, the result is a clear image. For the nearsighted, the glasses must pre-distort the image one way. For the farsighted, the image must be pre-distorted in the opposite way. The lenses of the glasses must be shaped to match a particular sight problem. In the same way, the linearizers LTI produce must be tuned to cancel the distortion of a particular non-linear amplifier.
LTI is a small, independently owned and operated firm specializing in the solution of problems involving non-linearity at microwave frequencies, and the production of related satellite hardware. LTI has a 21,000 sq. ft. facility that supports both R & D and manufacturing, and is conveniently located in the Princeton Region of New Jersey. This facility incorporates the entire manufacturing process from RF/microwave/millimeter-wave research and development through to the production phase. The facility includes a microwave, electrical and environmental/ vibration test area, a class 10,000 clean room with wire-bonding, ribbon welding, die attach, and microelectronic assembly capabilities, compliant to MIL-PRF-38534. LTI facilities have the capability to make vector measurements beyond 70 GHz. All assembly personnel are trained and certified to the NASA solder standard. A computer network with an array of PCs is available for both office and engineering needs. LTI engineers have developed a number of proprietary programs for the analysis and design of linearizers. These are used in conjunction with commercial software to meet their design needs.
LTI maintains a close relationship with subcontractors in printed circuit board design, prototype machining, and various electronic parts manufacturers. We are ISO 9001:2008 certified, and hold to MIL-STD-883 in a lean production environment.
LTI has the staff, test facilities and research background to resolve distortion problems due to all forms of non-linearity. Our state of the art in-house facilities accommodate work from dc up through millimeter wave frequencies and photonic applications. Over the past 12 years, our primary R & D experience has been in the development of predistortion linearizers using passive and active devices, and more recently digital techniques. We also have experience with feed forward, feed back and other forms of linearization. We have a highly experienced system analysis group that has developed proprietary software to assist in the design and test of linearizers, and to evaluate the potential benefits from linearization.
