RF9938: Low-Cost HBT Upconverters for CDMA Transmitter ICs
To support the increasing demand for Code Division Multiple Access (CDMA), the latest digital munication technology in cellular industry, RF Micro Devices (RFMD) developed CDMA chip sets for both receiver and transmit chain. The CDMA chip sets were designed and manufactured on an advanced GaAs Heterojunction Bipolar Transistor (HBT) process from TRW. The HBT process offers several advantages over other processes such as high Ft, low noise transistors, and process consistency. The CDMA program is two-fold. The first chip set, which was designed for cellular...
