Scintera Networks

Scintera Networks operated as a fabless semiconductor company, establishing its presence in the market in 2001. The company was co-founded by Abhijit Phanse, who also served as the initial President and CEO, and Dr. Abhijit Shanbhag, who took on the role of chief systems architect. Phanse brought a decade of experience from National Semiconductor, where he led the development of communication ICs for high-speed LAN and optical networking. Dr. Shanbhag's background included roles at Qualcomm and Ericsson, with over ten years of experience in advanced communication systems architectures. The executive team was later strengthened by Davin Lee, who assumed the CEO position, leveraging his experience from Intersil.

The firm specialized in developing high-frequency, signal-processing technology designed to measure, modify, and monitor radio frequency (RF) signals and systems. Scintera's business model revolved around providing these semiconductor solutions to a global client base of cellular and broadcast infrastructure customers. Its core technology was a programmable analog signal processing architecture, which blended the flexibility of digital programming with the low power consumption and small size characteristic of analog circuits. A key product line was the family of adaptive RF power amplifier linearizers (RFPAL), which addressed the critical need for power efficiency in wireless communications. These system-on-chip (SoC) solutions, such as the SC1887 and SC1894, were designed to be inserted directly into transmitter designs, significantly reducing power consumption, complexity, and cost compared to traditional digital pre-distortion (DPD) methods. The RFPAL technology could improve a power amplifier's efficiency by up to four times, a considerable advantage for clients in the small cell base station, repeater, and broadcast system markets.

Scintera's journey included a strategic investment from Maxim Integrated Products in 2012, a partnership aimed at developing power-efficient small cell base stations. This collaboration highlighted the industry's shift towards smaller, more cost-effective network solutions. Ultimately, Scintera Networks was acquired by Maxim Integrated Products on February 27, 2014, marking a significant milestone in its history.
