Anadigics Adds Three New Small-Cell Power Amplifiers

Small cell range addresses most popular WCDMA, LTE FDD and TD-LTE frequency bands

Anadigics has introduced three new power amplifiers (PAs) optimised for 3G and 4G small-cell applications, including picocells, enterprise-class femtocells, and high-performance customer premises equipment (CPE). The amplifiers are built using the company's InGaP-Plus technology.

The AWB7133, AWB7137, and AWB7238 operate in the 2496 MHz to 2690 MHz, 758 MHz to 803 MHz, and 791 MHz to 821 MHz frequency band, respectively, delivering a combination of efficiency, linearity, output power, and thermal characteristics ideally suited to small-cell applications.  

"Anadigics continues to expand its industry-leading small-cell power amplifier family to address the most popular WCDMA, LTE FDD and TD-LTE frequency bands," said Charles Armour, senior director of business development for Wireless Infrastructure Products at Anadigics.  "As wireless data consumption continues to break records, our power amplifiers enable the design of high throughput, reliable, and compact small-cell base stations.  These solutions enable service providers to economically and pragmatically expand broadband network capacity and coverage."

 The AWB7133 and AWB7137 power amplifier devices deliver better than 15 percent efficiency, 28 dB gain, and -47 dBc ACPR @ +24.5 dBm of linear output power.  The AWB7238 power amplifier features 13.5 percent efficiency, 30 dB gain, and -47 dBc ACPR @ +27 dBm linear output power.   

These power amplifiers are available in the compact, low-profile 7 mm x 7 mm x 1.3 mm surface mount package used across theAWB71XX and AWB72XX product lines, allowing the same PCB layout to be used for different bands and power levels.  Anadigics' small-cell power amplifiers offer integrated bias, which eliminates the need for complicated external circuitry and reduces PCB space requirements.

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.
