Scintera Reaches Major Milestone with its Adaptive RF Power Amplifier Linearizer SoC

The SC1887 has been deployed in CDMA and WCDMA systems including repeaters, remote radio heads and microwave point-to-point applications where standalone operation, high performance and long-term reliability are critical. Adoption is also quickly increasing in the UHF digital terrestrial broadcast market. Customers are enjoying 2x to 4x improvements in transmitter chain efficiency compared to their previous solutions operating in back off.

“We are pleased to announce this important milestone as it validates our innovative RF power amplifier (PA) linearizer family of products as being well suited for the most demanding cellular infrastructure applications. We are seeing strong customer demand and are continuing to ramp up production,” said Davin Lee, chief executive officer of Scintera. “The SC1887 is filling the large gap between costly and difficult-to-implement active linearization solutions like digital predistortion and inefficient and power-hungry passive linearization, where the PA is operated in back off.”

The SC1887 is packaged in a standard 64-pin, 9 x 9 mm QFN package enabling the implementation of the entire predistortion and linearization solution in less than 9 cm2 of board space. The compact solution is easily integrated directly into the most restricted form factors including PA modules.
