2.5 GHz to 2.7 GHz  
WiMAX Power Amplifier  
ADL5571  
FEATURES  
GENERAL DESCRIPTION  
Gain: 29 dB  
The ADL5571 is a high linearity 2.5 GHz to 2.7 GHz power  
amplifier designed for WiMAX mobile terminals and CPEs  
using TDD operation at a duty cycle of 50% or lower. With a  
gain of 29 dB and an output compression point of 31 dBm, it  
can operate at an output power level up to 27 dBm while  
maintaining an EVM of ≤3% with a supply voltage of 5 V. PAE  
is 21% at POUT = 25 dBm with a 3.3 V supply voltage.  
Operation from 2.5 GHz to 2.7 GHz  
EVM ≤ 3% with 16 QAM OFDMA  
@ POUT = 25 dBm (3.3 V, 2.6 GHz)  
@ POUT = 27 dBm (5 V, 2.6 GHz)  
Input matched to 50 Ω  
Power supply: 3.2 V to 5 V  
Quiescent current: 135 mA  
Power-added efficiency (PAE)  
21% @ POUT = 25 dBm (3.3 V, 2.6 GHz)  
Multiple operating modes to reduce battery drain  
Standby mode: 9 mA  
The ADL5571 RF input is matched to provide an input return  
loss of better than 10 dB. The open-collector output is externally  
matched with a microstrip line and an external shunt capacitor.  
The ADL5571 operates over a supply voltage range from 3.2 V  
to 5 V with a current of 450 mA burst rms when delivering  
25 dBm (3.3 V supply). A standby mode is available that reduces  
the quiescent current to 9 mA, which is useful when a TDD  
terminal is receiving data.  
Sleep mode: <1 μA  
APPLICATIONS  
WiMAX mobile terminals and CPEs  
The ADL5571 is fabricated in a GaAs HBT process and is packaged  
in a 4 mm × 4 mm, 16-lead, Pb-free, RoHS-compliant LFCSP  
that uses an exposed paddle for excellent thermal impedance. It  
operates from −40°C to +85°C.
