Scintera Network recently revealed that its RF Power Amplifier Linearizer also known as RFPAL SC1889 has been incorporated in a quad-band 20W-60W optical repeater and a dual-band 20W remote radio unit. SK Telecom's (News - Alert) network rollout of 4G LTE includes the implementing these components which will also assist in enhancing the network performance of current 2G/3G services.
SKT has implemented Scintera's SC1889 linearizers in its two systems, namely the 1.2G/3G/4G Quad-Band Optical Repeater and the 2.4G Dual-Band Remote Radio Unit. The optical repeater is compatible with LTE (News - Alert), CDMA and WiBro, and can support a maximum wide signal bandwidth of 55MHz. The radio unit features an output power of 20W and is compatible with LTE.
In a statement, Sang Ho Kim, manager, Access Network Development, SKT said, "Scintera's linearizer is playing an important part in our rollout of 4G services. Timely delivery of systems, low power consumption, high performance and compact overall volume were key areas of focus for SKT. The Scintera SC1889 allowed our suppliers to meet all those requirements enabling our subscribers to enjoy the improved coverage and speed of our new data services."
All the suppliers of SKT will be able to develop condensed, power proficient and affordable radio units in a speedy manner using Scintera's technology, fulfilling extremely rigorous performance and quality criteria. SKT will not only be able to implement and administer its LTE network in an enhanced manner, but also be able to extend coverage for its subscribers across Korea.
Davin Lee (News - Alert), CEO, Scintera added, "We are pleased to be incorporated in SKT's LTE network rollout. Korea's cellular operators recognize Scintera's value in enabling the quick design of compact, cost effective and high performance solutions. The selection of Scintera by key global operators such as SKT reinforces RFPAL's robustness and value for next generation wireless infrastructure systems. SKT views Scintera's RFPAL as a key component in lowering equipment, deployment and maintenance costs and we see this trend accelerating across the world."
The SC1889 from Scintera is currently available for commercial use. As compared to other competitive offerings, Scintera's RFPAL architecture provides considerable benefits in terms of reduced expense and time to market when deployed in standard CMOS.
