MAX4473功放(PA)控制 IC 极大简化了 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
The MAX4473 PA control IC greatly simplifies the power ramp-up and ramp-down control circuitry required by PA in GSM or other TDMA cell phones. The IC is available in a tiny 8-pin μMAX package (3mm × 5mm) to replace the three op amps required for discrete solutions and
