Anadigics Introduces Six PAs For TD-LTE Small-Cell Use

Wireless infrastructure PAs deliver efficiency and linearity for picocells, femtocells and CPE Devices

Anadigics has launched six new power amplifiers optimised for 4G TD-LTE (Time-Division Long-Term Evolution) small-cell applications.  While LTE FDD is the dominant global standard for LTE services today, TD-LTE networks are being rolled-out by several major carriers, including China Mobile.  According to a recent report by DIGITIMES Research, worldwide TD-LTE subscribers are forecasted to increase from 12.48 million at the end of the first quarter of 2014 to 276.2 million at the end of 2016.

Built on Anadigics' InGaP-Plus technology, the new AWB7031, AWB7032, AWB7228, AWB7231, AWB7232 and AWB7239 TD-LTE power amplifiers are optimised for small-cell applications, including picocells, enterprise-class femtocells, and high-performance customer premises equipment (CPE).  These devices are said to deliver an industry-leading combination of output power, linearity, power-added efficiency and thermal characteristics.  

Anadigics says its small-cell power amplifiers enable manufacturers to develop compact wireless infrastructure solutions that are more thermally-efficient, consume less power, enable higher throughput, and provide greater coverage and range.

"TD-LTE networks are quickly adding subscribers as a variety of providers adopt this high performance standard," said James Martin, senior director of business development for Infrastructure Products at Anadigics.  "Our new TD-LTE solutions deliver optimal performance for the newest generation of small-cell devices and solidify our position as a leader in the wireless infrastructure market.  With the highest linearity and efficiency in their class, Anadigics' TD-LTE small-cell power amplifiers offer an economical path for providers to expand broadband network coverage in support of more subscribers."

The AWB7031 and AWB7032 power amplifiers are optimized for 1/4 Watt linear output power applications and featured in compact 5 mm by 5 mm packages.  The AWB7228, AWB7231, AWB7232 and AWB7239 power amplifiers deliver +27 dBm output power for 1/2-Watt linear output power applications.  These new small-cell power amplifiers also support the short turn-on-time requirements of TD-LTE applications.

AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
