Single 5 V power supply Small footprint 8-lead LFCSP Pin compatible with 15 dB gain ADL5541 1 kV ESD (Class 1C) GENERAL DESCRIPTION The ADL5542 is a broadband 20 dB linear amplifier that The ADL5542 is fabricated on an InGaP HBT process and has operates at frequencies up to 6 GHz. The device can be used in an ESD rating of 1 kV (Class 1C). The device is packaged in a a wide variety of CATV, cellular, and instrumentation equipment. 3 mm 3 mm LFCSP that uses an exposed paddle for excellent thermal impedance. The ADL5542 provides a gain of 20 dB that is stable over frequency, temperature, power supply, and from device to The ADL5542 consumes 93 mA on a single 5 V supply and is device. The device is internally matched to 50 with an input fully specified for operation from 40C to +85C. return loss of 10 dB or better, up to 6 GHz. Only input/output A fully populated RoHS-compliant evaluation board is ac coupling capacitors, power supply decoupling capacitors, and available. an external inductor are required for operation. The ADL5541 is a companion part that offers a gain of 15 dB in a pin-compatible package. Rev. C Document Feedback Information furnished by Analog Devices is believed to be accurate and reliable.
