LAFOX, ILRichardson Electronics Ltd. has teamed with Scintera, Inc. to bring Scintera's SC1887 system-on-a-chip (SoC) to market. The SC1887 promises to deliver power-amplifier (PA) linearity improvements without requiring access to in-phase/quadrature (I/Q) baseband signals. The SoC supposedly eliminates any need for software development. Because the SC1887 automatically calibrates and adjusts to the signal environment, a training algorithm is not required.

The SoC is designed to deliver adjacentchannel- leakage-ratio (ACLR) improvements to 26 dB. It also claims to increase PA power output power while maintaining linearity. The SC1887 requires less than 15 additional passive components, and eliminates the need for analogto- digital or digital-to-analog converters.

"By making small modifications to an existing RF amplifier design, we now have the ability to enable our customers to quickly design-in this important new power-amplifier enhancement technology," says Chris Marshall, Vice President of RF & Microwave Components for Richardson Electronics. "Scintera's technology allows RF-amplifier designers to achieve the newest performance specifications with relative ease. This technology improves Class AB and Doherty PA performance for CDMA, WCDMA, WiMAX, TD-SCDMA, CDMA2000, DVBH, MediaFLO, multicarrier-GSM, and LTE applications."

Kris Rausch, Vice President of Sales and Marketing at Scintera, Inc., adds, "We are proud to team up with Richardson Electronics to bring the system-on-a-chip to market. Its global team of field-applications engineers will provide the proper level of support for OEM design engineers seeking to improve performance on existing RF amplifier designs or to create something entirely new for their specific application."
