Optichron (News - Alert) unveiled today its OP5000 Crest Factor Reduction integrated circuit (CFR IC). The circuit is designed to reduce the peak-to-average ratio of signals across all protocols. Key OP5000 offers interpolation options, in addition to six programmable filters which are configurable on a channel-by-channel basis. This permits selective channel efficiency improvements, and at the same time meets the error vector magnitude requirements of multi-mode operations like HSDA and WCDMA. PAR reduction lets designers working with data-centric technologies enhance the efficiency of costly power amplifiers, while simultaneously maintaining spectral compliance allowing an increase in the operating point while.

 

"Optichron's OP5000 offers designers a flexible, modulation-agnostic CFR solution that efficiently reduces signal PAR," said Optichron CEO Perry Constantine. "The combination of the OP5000 CFR and the OP4400 DPD improves efficiency and performance to best-in-class levels while enabling a more highly integrated RF system for lower cost. Optichron continues to expand our portfolio of signal optimization products with flexible solutions that enable designers to optimize their RF designs more easily and effectively."

 

Designers have the option of using the OP5000 CFR with Optichron’s OP4400 digital pre-distortion ICs--a combined solution which improves efficiency and linearity to deliver excellent PA performance. Target applications include WCDMA, GSM, WiMAX, CDMA2000, LTE (News - Alert) and point-to-point RF applications utilized in high-end infrastructure equipment and customer premise equipment.
