GENERAL DESCRIPTION
The ADL5570 is a high linearity 2.3 GHz to 2.4 GHz power
amplifier designed for WiMAX 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 26 dBm while maintaining an EVM
of ≤3% with a supply voltage of 3.5V. PAE is greater than 20% at
P
OUT
= 25 dBm with a 3.5V supply voltage.
The ADL5570 RF input is matched on chip and provides an
input return loss of less than 10 dB. The open-collector output
is externally matched with strip-line and external shunt
capacitance.
The ADL5570 operates over a supply voltage range from 3.2 V
to 5.5 V with a supply current of 400mA Burst RMS when
delivering 25 dBm (3.5 V supply). A low power mode is also
available for operation at power levels ≤10 dBm with optimized
operating and quiescent currents of 100 and 70 mA,
respectively. A Standby mode is available which reduces the
quiescent current to 10 mA: useful when a TDD terminal is
receiving data.
The ADL5570 is fabricated in a GaAs HBT process and is
packaged in a 4mm x 4mm 16-Lead Pb-free RoHS compliant
LFCSP that uses an exposed paddle for excellent thermal
impedance. It operates from 40°C to +85°C.
