RX IF/BBA WITH GPS S1M8662A (Preliminary) INTRODUCTION S1M8662A is CDMA/PCS/GPS Triple Mode IF/ baseband IC which is divided into three main parts - IF frequency processing, basband processing , and digital interface. The receiver IC (S1M8662A)and transmitter IC (S1M8657) are provided as a KIT. S1M8662A is a receiver IC, installed with a Rx AGC, Baseband Converter, Baseband analog filter, and A-D Converter. It can send a digital baseband signal to the digital baseband IC. S1M8662A is fabricated on the Samsung's 0.5um high-speed, high frequency BICMOS processing and can achieve superior high frequency and low power digital operations. Its operating voltage is 2.7 to 3.3V, and operating temperature -30 to +85°C . 32-BCC++-5.0×5.
