Fairchild Semiconductor recently released the RMPA0965, an RF power amplifier optimized for CDMA2000-1X applications in the 824-849 MHz frequency band for today's rapidly evolving handset requirements.
The RMPA0965's single positive-supply operation, low power and shutdown modes provide 40 percent CDMA mode efficiency at +28 dBm average output power. When used in CDMA cell phone applications, the device's high/low power modes optimize battery talk-time and reduce current consumption during peak phone usage.
The two-stage RMPA0965 power amplifier is matched to 50 Ohms on both the input and output. This matching minimizes the need for external components, thereby reducing Bill of Material (BOM) part count and simplifying designs. The high poweradded efficiency (PAE) and excellent linearity of this product are achieved using Fairchild's proprietary InGaP Heterojunction Bipolar Transistor (HBT) process. The RMPA0965's LCC package also provides industry standard pin-out. This product greatly enhances Fairchild's position in the CDMA handset market. The RMPA0965 was recently integrated into the next-generation platform of one of Korea's leading handset manufacturers, with production beginning this month.
In addition to the new RMPA0965, Fairchild's extensive portfolio of highvolume components for the wireless communications industry includes HBT and pHEMT GaAs MMICs, transmit modules and components for handsets, WLAN systems, wireless base stations, data communications systems, and millimeter wave systems.
