MAX2251中文资料+2.8V、单电源、蜂窝频段线性功率放大器数据手册ADI规格书

描述 Description

The MAX2251 low-voltage linear power amplifier (PA) is designed for TDMA/AMPS dual-mode phone applications. The device is packaged in an ultra-compact (2.06mm x 2.06mm) chip-scale package (CSP), and delivers over +30dBm of linear power in TDMA operation. An on-chip shutdown feature reduces operating current to 1µA (typ), eliminating the need for an external supply switch.
The MAX2251 does not need an external reference voltage, and requires only a few external matching components and no bias circuitry. Another feature of this device is the use of external bias resistors, eliminating wasted \"safety-margin\" current. This feature also allows current throttleback at lower output power levels, thereby maintaining the highest possible efficiency at all power levels.

特性 Features

• High Efficiency—41% at +30dBm POUT (TDMA) (typ)
• ICC A = -40°C to +85°C
• No External Logic Interface Circuitry Required

应用 Application

• 双向寻呼器
