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
