Javelin's PAs measured in actual handsets have achieved excellent linearity and the best noise performance of any 3G PA on the market today, which improves overall handset performance by minimizing interference with other 3G, GSM, GPS, WLAN and Bluetooth radios in smartphones. Javelin’s PAs feature the highest ESD rating in the industry, passing 3 kV on all pins, which enables higher manufacturing yields. Also, with CMOS integration, the JAV5502 is the first PA to support a MIPI digital interface for advanced features including power control.
