Power AmplifiersIn 2006, Anadigics shipped multi-mode, multi-band power amplifiers (PAs) to Samsung for the SGH-Z620 3G handset. With a profile of only 11.8 mm, the SGH-Z620, also known as the Ultra Edition 11.8, was a sleek handset that features a 2 megapixel camera, HSDPA connectivity, and QVGA display. The single-package penta-band WCDMA/EDGE PAs significantly reduced space requirements, enabling manufacturers to design thin multimedia handsets.

Multi-mode, multi-band power amplifiers (PAs)

Multi-mode, multi-band power amplifiers (PAs) are integral components in modern wireless communication systems, such as mobile devices and base stations. These power amplifiers can operate across multiple frequency bands and support various communication standards or modes, such as GSM, CDMA, WCDMA, LTE, and 5G. The ability to work in different modes and bands is vital as it allows a single device to communicate over different networks, both nationally and internationally. This versatility is particularly important in a globalized world, where interoperability across different networks is key. These power amplifiers play a critical role in converting low-power radio frequency signals into higher power signals, making it possible for data to be transmitted over long distances. The advancements in PA technology, such as envelope tracking and digital pre-distortion, have led to more efficient power usage, better signal quality, and longer battery life for mobile devices.
