GENERAL DESCRIPTION
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 P
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.
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.
