The ADL5541 is a broadband 15 dB linear amplifier that operates at frequencies up to 6 GHz. The device can be used in a wide variety of CATV, cellular, and instrumentation equipment.The ADL5541 provides a gain of 15 dB, which is stable over frequency, temperature, power supply, and from device to device. 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 ADL5541 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 ADL5541 consumes 90 mA on a single 5 V supply and is fully specified for operation from −40°C to +85°C.A fully populated RoHS-compliant evaluation board is available.The ADL5542 is a companion part that offers a gain of 20 dB in a pin-compatible package.
