GENERAL DESCRIPTION
The device is internally matched to 50 Ω with an input return loss of 10 dB or better, up to 6 GHz. Only input/output ac coupling capacitors, power supply decoupling capacitors, and an external inductor are required for operation. The ADL5542 is fabricated on an InGaP HBT process and has an ESD rating of 1 kV (Class 1C). The device is packaged in a 3 mm × 3 mm LFCSP that uses an exposed paddle for excellent thermal impedance. The ADL5542 consumes 93 mA on a single 5 V supply and is fully specified for operation from −40°C to +85°C.
