44 dBm at 500 MHz 40 dBm at 900 MHz Output 1 dB compression: 19.7 dBm at 900 MHz Noise figure of 3.5 dB at 900 MHz Single 5 V power supply Small footprint 8-lead LFCSP Pin compatible with 20 dB gain ADL5542 1 kV ESD (Class 1C)
GENERAL DESCRIPTION
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.
