Outstanding amplifier linearity results from a small R&D investment

Richardson Electronics, Ltd. (NASDAQ: RELL), announced today it has teamed with Scintera, Inc. to bring Scintera's recently announced SC1887 to the worldwide market. The SC1887 delivers critically needed power amplifier linearity improvements without requiring access to the I/Q baseband signals. This digitally controlled analog technology works at the RF signal level, can be brought to market quickly, and requires only the addition of a few standard RF components to implement. Scintera's SC1887 Adaptive RF Power Amplifier Linearizer is a practical, cost-effective solution that satisfies today's needs for reduced amplifier distortion, increased power efficiency, and higher output power.

"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^TM, 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 our SC1887 system-on-chip (SoC) 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. In either case, design engineers are discovering that the SC1887 is an elegant solution that reduces development costs and speeds time-to-market for their amplifier design improvement projects."

Benefits of this new technology for RF Power Amplifier (PA) designers include:

• Access to I/Q baseband signals is not required
• No software development required (reduced time-to-market)
• No digital R&D team required (lower development cost)
• No training algorithm development or special control required - the SC1887 automatically calibrates and adjusts to the signal and the existing PA environment
• Up to 26 dB ACLR (Adjacent Channel Leakage Ratio) improvement
• Increase power output levels while maintaining linearity requirements
• Low cost - no A/D or D/A converters needed
• Minimal part count - less than 15 additional passive components needed

Richardson Electronics' field sales engineering teams are working with customers right now to help design-in this new Scintera solution. To support this initiative, Richardson Electronics also sells Scintera evaluation kits that can be used to test and evaluate the key features of the SC1887, as well as for PA design integration purposes.
