TriQuint To Introduce New GaAs High Power Amplifiers At 2006 European Microwave Week (EuMW) Exhibition

HILLSBORO, OR & RICHARDSON, TX - September 11, 2006 - TriQuint Semiconductor (Nasdaq: TQNT), a leading supplier of microwave and millimeter wave products for wireless communications infrastructure and high-reliability communications systems, will introduce two new high-OTOI (output third order intercept) gallium arsenide (GaAs) amplifiers during the European Microwave Week Exhibition (12th-14th September) in Manchester, UK. These new advanced design amplifiers are part of TriQuint’s continuing commitment to meet customers’ market-specific high frequency signal amplification needs while also providing smaller, lower-cost alternatives compared to previous-generation products.

TriQuint’s new amplifiers (TGA4530 and TGA4530-SM) are designed for point-to-point radio, K-band satellite communications and point-to-multipoint network infrastructure applications. These new products offer designers industry-leading OTOI performance (for higher data rates, improved system efficiency and longer range transmission) in both MMIC form and in low-cost, industry-standard plastic surface mount packages. Additional product benefits include an on-chip power detector to reduce the bill of materials and a protective surface passivation layer for environmental robustness.

"TriQuint remains committed to providing the highest performance millimeter wave power amplifiers in the industry. The TGA4530 linear HPAs (high power amplifiers) are the latest addition to our extensive product portfolio. The market for low-cost, industry standard packaged millimeter wave power devices continues to increase. By working closely with our customers we have been able to significantly improve the performance and lower the cost of millimeter wave amplifiers by investments in device modeling, design and testing to support the demand for high power millimeter wave MMIC and packaged devices," said Dan Green, TriQuint Broadband Products Marketing Director. "The TGA4530 will be offered in both a surface mount package and as a die product to provide the flexibility in delivery format that our customers require."

TriQuint’s TGA4530 linear HPA’s benefits and performance specifications include a frequency coverage of 17-21 GHz for applications including point-to-point radio, K-band satellite communications and point-to-multipoint radio. The TGA4530 provides 41 dBm OTOI, 29 dBm output power at the 1 dB compression point at a bias of 6V (825mA, Idq); typical gain is 21 dB with input and output return losses of 15dB. The small size of the MMIC is achieved using TriQuint’s proven 0.25-micron power pHEMT 3MI (3-metal-layer interconnect) production process. The TGA4530 also incorporates an on-chip power detector, thus reducing the bill of materials by eliminating the need for a discrete power detection circuit. The TGA4530 is the MMIC version; the TGA4530-SM is packaged.

Evaluation boards are available upon request; these products are lead-free and RoHS compliant. Data sheets for the two products are available at:
