RX IF/BBA WITH GPS

S1M8662A (Preliminary)

1

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 .
