MAX2248

1.9GHz Power Amplifier

Industry's Only DECT PA with Digital Power Control


点击查看特定型号的库存状况。

说明

The MAX2248 single-supply, low-voltage power amplifier (PA) IC is designed specifically for applications in the 1880MHz to 1930MHz frequency band. The PA provides a +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 +4dBm 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 MAX2248 integrates the RF input and inter-stage 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.

This part is packaged in a 3mm x 3mm, 16-pin TQFN.
