2.3 GHz TO 2.4 GHz WiMAX Power Amplifier
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 4.2 V with a supply current of 440 mA burst rms when delivering 25 dBm (3.5 V supply). A low power mode is also available for operation at power levels of ≤10 dBm with optimized operating and quiescent currents of 100 mA and 70 mA, respectively. A standby mode is available that reduces the quiescent current to 1 mA, which is useful when a TDD terminal is receiving data.
The ADL5570 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.
