GaAs Technology Leadership

USTI has been producing state-of-the-art GaAs semiconductor components since 1984. These devices have made possible unique system solutions for a broad spectrum of wireless system applications from 400 MHz up to 40 GHz. This long history of experience and leadership allows the Company to best leverage the most from a technology well suited for high-frequency, low voltage and efficient linear applications required by today’s wireless communications terminal and infrastructure designers.

USTI’s GaAs products are produced using implanted MESFET as well as epitaxial and pHEMT structures. By having a variety of options, the Company selects the best fit for a given product function based on achieving maximum, cost-effective performance. In addition, USTI continues to explore new and emerging GaAs-based technologies as they become available.

Maximizing performance in the most cost-effective way possible is the focus of USTI’s semiconductor product designs. Dedicated to solving the needs of end applications, USTI products have been designed and optimized for the specific modulation standards in which they will perform. This means linear, efficient, small, cost-effective and powerful solutions can be yours.

USTI products are designed to provide maximum performance while occupying very little circuit board real estate and, where possible, are surface mountable. In many instances USTI product solutions can reduce by as much as one-third the space requirements of alternative technologies.

USTI products are ideally suited for a number of transmit frequency applications including cellular 800 MHz – 1.0 GHz), satellite (1.6 – 1.7 GHz), PCS (1.8 – 2.0 GHz), and WLAN/Wireless local loop (2.2 – 2.7 GHz). Modulation formats as varied as GSM, TDMA, CDMA, DCS, PHS and other are all supported. Power GaAs RF ICs and discrete power FETs form the backbone of USTI’s diverse product offerings.

If customers have unique system requirements contact USTI first. In most cases USTI can provide performance data and information as to how a specific product will function. Select receive products, offerings high levels of integration and dynamic range, can form complete chip set solutions.

USTI is also a manufacturer of radio transceiver subsystems, transceiver components and radios. As a result, the company understands the unique system trade-offs associated with many wireless system requirements. This experience provided the necessary link between strong products and a realization of the overall solution to the designer’s system needs.

In most cases, application support is one of the key ingredient to over-all success. USTI is committed to superior application support services. USTI’s engineering team can provide proven schematics and layouts, and critique any end application to best ensure prototype success. In this way, the performances of USTI products are realized early-on in the designer’s system.

USTI products are assembled in-house and at local subcontractors, as well as offshore. Along with the security of multiple sources, this provides the Company with a unique ability for rapid reaction to meet the needs of existing product production and quick time-to-market of new products.

As a leading supplier of high-frequency GaAs components USTI has developed unique strengths in high-volume and accurate RF testing. In many cases the testing environment is the same as the application circuit in which the product will perform. This means guaranteed RF performance within the most meaningful environment possible. For complex modulation requirements, products are tested for performance under the actual modulation specifications – giving further confidence that USTI products will offer the best performance obtainable in your system design.

USTI GaAs-based products are proven and robust. All products undergo rigorous qualification and testing procedures based on long established, tough, military standards. In most cases, these standards have qualified USTI’s products for use in some of the most demanding military and space applications imaginable.
