5GHz Linear Power Amplifiers

General Description

Features

The MAX2840/MAX2841 low-cost linear power ampli-

fiers (PAs) operate in the 5GHz to 6GHz band. The PAs

are designed for high gain and high linearity, which

makes them ideal for use in IEEE 802.11a OFDM sys-

tems. The MAX2840 delivers +15dBm output power,

and the MAX2841 delivers +18dBm output power.

✕ 5GHz to 6GHz Operating Frequency Range

✕ High Linear Output Power

+15dBm at 5.25GHz (MAX2840)

+18dBm at 5.25GHz (MAX2841)

✕ 22dB Power Gain

The devices integrate a power detector that provides

over 15dB dynamic range and 1.0dB accuracy. ꢀith

the detector circuit built in, an automatic level control

(ALC) function can be easily implemented.

✕ On-Chip Detector With 15dB Dynamic Range and

±1.0dB Detector Accuracy

✕ Simple Input and Output Matching

The PAs also feature an external bias control function.

The idle current can be adjusted through an external

DAC to improve efficiency at reduced output powers

while maintaining sufficient ACPR and EVM perfor-

mance. As a result, the highest possible efficiency is

maintained at all power levels. The MAX2840/MAX2841

operate over a single +2.7V to +3.6V power-supply

range. An on-chip shutdown feature reduces operating

current to less than 10µA, eliminating the need for an

external supply switch.

✕ +2.7V to +3.6V Single Supply

✕ Shutdown Mode With Less than 10µA Current

✕ 2mm ✕ 1.5mm Chip-Scale Package
