The firm’s new base station modules offer designers four levels of RF integration to reduce board space, lower bill of materials, and improve efficiency. Level 1 TriQuint solutions include high gain products that can replace one or more discrete components with a single module. At the highest level of integration, TriQuint’s new Level 4 modules such as the TQM879006, replace multiple discrete products with one module that incorporates two amplifiers, a digital step attenuator and all input/output matching circuitry.
saving and cost reduction benefits of integrated components.
“We appreciate the quality of TriQuint’s AH212 and AH420. These devices have enabled us to develop high power amplifiers for new LTE base station systems. The support we receive from TriQuint has helped us satisfy customer demands,” said Samsung Electronics RF Core Lab Senior Engineer, Jong-Hyun Lee.
Leading base station repeater manufacturer SK- Telesys also recognizes the benefits of TriQuint components in their WCDMA and CDMA systems.
“Our experience with TriQuint’s products including the AH212, AH225 and the ML485 has been very good. These devices enabled us to develop new repeater systems. Engineering and product support from TriQuint have been important for us in meeting customer deadlines and requirements,” said SK- Telesys Access R&D Senior Engineer, Chul Lee.
TriQuint products are used by major OEM base station radio manufacturers across Europe, Asia and North America in WCDMA, CDMA, MC-GSM and LTE networks.
“Global mobile networks are transitioning to base stations that use remote radio head designs. TriQuint’s newest products simplify RF connectivity in these systems. TriQuint devices enable manufacturers to focus on competitive system performance instead of dedicating valuable resources toward RF component matching issues,” said Brian P. Balut, TriQuint Vice President.
Huawei Networks touts the benefits of remote radio head designs in both trial and operational systems. In work with international mobile operator Vodaphone, Huawei notes in an article entitled, “Network Deployment; it’s all in the mind,” that the cost savings from increased efficiency in the links between the base station and the rest of the network are very significant. Remote radio head innovations are central to moving all key radio components closer to the antenna while reducing the size of radio housings; these advances reduce power consumption directly and through lower overall thermal mitigation requirements.
TriQuint base station customers including Samsung Electronics have benefitted from the space-

TriQuint offers integrated pre-driver and driver RFIC base station solutions designed to improve efficiency, reduce the PCB area dedicated to RF and reduce remote radio head bill of materials. TriQuint’s base station portfolio includes gain blocks, switches, mixers, low noise and driver amplifiers, converters, SAW filters and integrated modules.
Walmart Uses Innovative Thin Film Solar Technology to Increase Renewable Energy Use
Walmart announced today it will expand its renewable energy efforts through lighter, lower cost thin film solar technology.
The company plans to add solar generating systems to another 20 to 30 sites in California and Arizona, and the majority of these locations will
