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.
