SUNNYVALE, CA: ACCO Semiconductor is now into production of AC26120, a CMOS Multi-mode Multi-band Power Amplifier (MMPA) for smart phones and Internet of Things (IoT) applications. The product stands ahead of other CMOS power amplifiers to strengthen 2G and single-band 3G handsets.

AC26120 modifies the image of CMOS power amplifiers with its cost, design and supply-chain advantages of CMOS integration and competitive performance. ACCO has patented a unique transistor design - Gallium Arsenide (GaAs) power amplifiers in conjunction with the standard CMOS fabrication processes. This style of fabrication embeds the benefits of Moore’s Law to the final non-silicon structure in the phone – the RF frontend. The combination reduces the cost curves with the same set of functionalities and reliability as the others.

Compatibility with various brands of LTE phones is achieved as both Linear GSM and Vramp GSM are supported. AC26120 constitutes the smallest MMPA (5x5mm) and a low profile LGA package (0.69mm) for thin handsets. The technology covers multiple frequency bands ranging from 1 to 39 and operates in an allocated amplifier path for mid/low power mode to deliver best possible performance. In addition to integrating with GSM, EDGE, WCDMA, TD-SCDMA and LTE it also operates on MIPI and GPIO modes.
