TriQuint Semiconductors announced three new multi-mode, multi-band power amplifier modules (MMPAs) that deliver longer battery life for LTE smartphones while simplifying increasingly complex RF design. The new products that feature new envelope tracking technology as well as a new mobile chip interface, are said to be already capturing design wins in leading LTE smartphones.
Device manufacturers are adopting envelope tracking (ET) in next-generation smartphones to maximize energy efficiency. ET extends battery life by dynamically adjusting the supply voltage to the power amplifier (PA), in contrast to PAs with conventional constant-supply voltage. TriQuint's new MMPAs also feature a new mobile chip interface — based on an open "MIPI" standard — used by several chipset providers to increase interoperability among vendors and reduce development time and effort.
In addition to designing ever more sophisticated devices, smartphone manufacturers serving the global market must produce several regional variants of each model to operate in carriers' specific assigned spectrum. This is becoming more challenging as numerous new LTE bands are allocated. The versatile design of TriQuint's new MMPAs gives manufacturers a common platform to release new products at a faster pace, while controlling design and manufacturing costs. They support a growing number of popular 3G/4G bands for specific regions as well as quad-band GSM/EDGE. By integrating more functionality into smaller form factors, they simplify PCB routing, reduce BOM count and speed time to market.
