2.5GHz、22dBm/20dBm功率放大器，带有模拟闭环功率控制

MAX2244/MAX2245/MAX2246单电源、低电压功率放大器(PA)针对2.4GHz至2.5GHz下20dBm Bluetooth® 1类应用而设计。MAX2244/MAX2245可以在大于20dB的输出功率控制范围内提供22dBm的峰值输出功率。22dBm的输出功率除用于补偿PA与天线间的滤波器损失外，可以向天线提供20dBm输出。MAX2246可以提供20dBm的峰值输出功率，而电源电流减小30%。\n 该PA集成了功率检测器和闭环功率控制电路，可以在电源电压、温度以及输入功率的全范围内提供近乎恒定的输出功率。模拟控制输入电压可以精确地控制输出功率的大小。\n MAX22 \n• 在全温度、电源以及输入功率范围内实现精确的闭环输出功率控制 \n• 22dBm峰值输出功率(MAX2244/MAX2245) \n• 内置带宽受限的功率斜率控制 \n• 0.5µA关断电流 \n• 裸片级封装(1.56mm x 1.56mm);
