HONG KONG and SANTA CLARA, Calif., Apr. 26, 2022 /PRNewswire=KYODO JBN/--

Digital Enhancement Limited today announces the commercial launch of the Intel

FPGA-based Digital Front-End (DFE) IP solution, which provides high-performance

and high efficiency 5G radio solution across scalable multiple Intel FPGA

families.

With the continuous evolution of 5G & WiFi, RAN communication solutions such as

Remote Radio Units (RRU), repeaters and routers have increased requirements on

radio performance and system level power efficiency. From Massive-MIMO

Macrocell to Small Cell, the DFE technologies including DPD (Digital

Pre-Distortion) and CFR (Crest Factor Reduction) have been well recognized as

the key enabling and differentiating elements to satisfying demanding use cases

crossing different frequency bands, bandwidths, under different PA types and

output power combinations.

"Digital Enhancement is a start-up company focusing on building the world's

leading agile DFE technology, breaking the limitations of traditional DFE

solutions that are bandwidth constrained, require tight coupling of hardware

and with limited choices of power amplifiers. We are very pleased to have

in-depth collaboration with Intel in the past year to provide a joint

commercial DFE solution over FPGA for 5G base station mass production. This not

only fully validates the fast and lightweight implementation of Digital

Enhancement's DFE solution, but also its high-performance linearization and

cost effectiveness. Customer can also easily evaluate the overall RF system

performance based on different DPD models and PAs with our developed DETP, a

powerful testing platform with 3GPP signal generator, DFE and analysis

functions built-in," said Ziming Wang, Founder and CEO of Digital Enhancement.

The DFE IP "Hummingbird" series supports 3G/4G/5G communications, covering all

types of PA techniques, and can effectively reduce the Long-term Memory Effect

on GaN amplifiers. With Hummingbird IP, only minimum FPGA resource at a

relative low sampling rate is required to deliver the necessary performance to

linearize high power amplifiers for base station equipment under the use case

of 4T4R and 200MHz signal bandwidth. While delivering a high linear

performance, such as one that's better than -50dBc ACLR and less than 2.5% EVM

on a PA of more than 40% efficiency, the overall cost of the digital and RF

systems in RRUs can be also significantly reduced.

"PA non-linearity issue has been the most challenging problem in RU design for

more than three decades. With the need of RU to now support higher bandwidth

(e.g. in excess of 200MHz) in multi-band configurations at lower thermal

budget, it's critical to employ best-in-class DPD technology on a flexible and

scalable hardware portfolio as the solution to address; a wide variety of

different radio use cases. Intel's FPGA family, including Agilex, Stratix, and

Arria, have been designed for the efficient and flexible DFE implementations,

particularly with the industry's best performance per watt Intel Agilex FPGA

family. The combination of DPD technology from our partner Digital Enhancement

running on Intel FPGAs would offer one of the best choices to our customers for

radio design," said Mike Fitton, General Manager, Network Business Division of

Intel's Programable Solution Group.  

Next, Digital Enhancement will continue to scale up its collaboration with 5G

base stations and O-RAN vendors worldwide, and to expand the application of

miniaturized DFE in the WiFi and mobile device markets.
