Overview

Frequency Range: 1880MHz–1930MHz
High +20dBm Output Power
2-Bit Digital Power Control: Four Output Levels
Low 105mA Operating Current
0.5µA Low-Power Shutdown Mode Current
+2.7V to +5V Single-Supply Operation
Small 3mm x 3mm, 16-Pin TQFN Package

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.

Product Details

The MAX2248 evaluation kit (EVkit) simplifies evaluation of the MAX2248 power amplifier (PA). It enables testing of the device’s RF performance and requires no additional support circuitry. The EV kit’s signal inputs and outputs use SMA connectors to facilitate the connection of RF test equipment.

The MAX2248 EV kit is assembled with a MAX2248 and incorporates output-matching components optimized for 1880MHz to 1930MHz.

Applications

1.9GHz DECT (Cordless Phones, Wireless Headsets)
