MAX2240中文资料2.5GHz、+20dBm功率放大器IC，UCSP封装数据手册ADI规格书

描述 Description

The MAX2240 single-supply, low-voltage power amplifier (PA) IC is designed specifically for applications in the 2.4GHz to 2.5GHz frequency band. The PA is compliant with Bluetooth®, HomeRF, and 802.11 standards, as well as other FSK modulation systems. The PA provides a nominal +20dBm (100mW) output power in the highest power mode.
The PA includes a digital power control circuit to greatly simplify control of the output power. Four digitally controlled output power levels are provided: from +3dBm to +20dBm. A digital input controls the active or shutdown operating modes of the PA. In the shutdown mode, the current reduces to 0.5µA.
The IC integrates the RF input and interstage matching to simplify application of the IC. Temperature and supply-independent biasing are also included to provide stable performance under all operating conditions.
The IC operates from a +2.7V to +5V single-supply voltage. No negative bias voltage is required. Current consumption is a modest 105mA at the highest power level.
The part is packaged in the UCSP™ package significantly reducing the required PC board area. The chip occupies only a 1.56mm x 1.56mm area. The 3 x 3 array of solder bumps are spaced with a 0.5mm bump pitch.
