TriQuint Semiconductor, a 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. 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 high power amplifiers (HPA) 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 from 17 to 21 GHz for applications including point-to-point radio, K-band satellite communications and point-to-multipoint radio. The TGA4530 provides 42 dBm OTOI, 30 dBm output power at the 1 dB compression point at a bias of 7 V (825 mA, Idq); typical gain is 20 dB with input and output return losses of 15 dB. 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.
