The development of a digital signal synthesizer with integrated predistortion linearization (DSS/PDL) is proposed. The DSS/PDL will generate complex waveforms and predistort these waveforms so as to compensate for the distortion of high power amplifiers(HPAs). All signal generation and processing… More

"Over the past six months as part of a Phase I SBIR, Linearizer Technology, Inc. has been involved in the research and development of a digital signal processing system for signal synthesis and distortion correction to be used with UHF/microwave high poweramplifiers. During this period an approach… More

A high-efficiency RF high power amplifier (HPA) operating from 2 MHz to 2 GHz with low distortion and high efficiency will be developed. Digital distortion correction offers the capability of dramatically improving amplifier linearity, enabling operation at much higher levels and correspondingly… More

Power amplifiers (PAs) providing high linearity, high efficiency and operating over a wide bandwidth are often required for tactical applications. Unfortunately, these parameters tend to work in opposition. Generally the higher the linearity of an amplifier, the poorer the efficiency. Likewise… More

Power amplifiers that provide both high linearity and high efficiency are essential for the transmission of high data rate bandwidth efficient digital signals used in modern MILSATCOM communications. Achieving this objective at millimeter-wave frequencies is particularly challenging. Linearizer… More

Linearizer Technology, Inc. (LTI) in association with L-3 Communications Corporation, Electron Devices Division (L-3 EDD) proposes to develop a linearized E-band TWTA. The goal of this program is to develop, fabricate, and test a compact linear E-band microwave power module (MPM) providing a… More

Power amplifiers that provide both high linearity and high efficiency are essential for the transmission of high data-rate, bandwidth efficient signals used in MILSATCOM and avionics communications. Achieving this objective at millimeter-wave frequencies remains particularly challenging. … More

ABSTRACT: Power amplifiers (PAs), providing high linearity and efficiency, are essential for transmission of high data rate bandwidth efficient digital signals. Achieving this objective at millimeter-wave (MMW) is particularly challenging. LTI with L-3 EDD are teaming to develop a PA for 81-86… More

LTI has extensive experience producing analog predistortion linearizers for microwave and millimeter-wave bands. Its linearizers are higher order linearizers, based on correcting a PA"s transfer characteristics without cancelling specific order IMD products. LTI designs when integrated with… More
