Scintera Networks announced the availability of the SC1869 and SC1889 second generation system-on-chip (SoC) adaptive RF Power Amplifier Linearizers (RFPAL) to address 3G and 4G heterogeneous network deployments. The SC1869/89 are said to enable manufacturers to increase the efficiency of their linear RF power amplifiers by two to four times while at the same time reducing size, complexity and cost. They build on the performance offered by existing RFPAL products for CDMA and WCDMA and expands supported standards to include WiMAX, EVDO, HSDPA, LTE, TD-LTE and LTE Advanced. The SC1869 specifically targets lower power amplifiers as typically found in emerging small cells required for data centric 4G cellular networks. The SC1869 can be configured to consume less than 400 mW while delivering desirable linearization performance.
