... TX RF FRONTS-ENDS IC INTRODUCTION S1M8674 is a fully integrated RF transmit IC for CDMA handsets. It includes an upconverter, a two-stage driver amplifier, and an LO buffer in 20TSSOP/24QFN (with exposed paddle) package. The driver amplifier delivers over 4dBm output power with -65 dBc/30kHz ACPR while drawing total current of under 40mA from 3.0V supply. The maximum output power is larger than 10dBm for AMPS application ...
