MAX 4473功放 (PA)控制 IC极大地简化了GSM或其它 TDMA蜂窝电话中 ,PA所要求的功率斜升和斜降控制电路。该 IC采用小巧的 8引脚μMAX封装 (3mm× 5mm) ,可替代分立方案所需的三只运放和大量无源元件 ,节省布局和设计时间 ,并有效地解决了多种 RF噪声和稳定性设计问题。MAX4473
The MAX 4473 PA control IC greatly simplifies the power ramping and ramp-down control circuitry required by PA in GSM or other TDMA cell phones. The compact 8-pin μMAX package (3mm × 5mm) replaces the three op amps and the large number of passive components required for discrete solutions, saving layout and design time and effectively addressing a wide range of RF noise and stability Sexual design issues.
