GENERAL DESCRIPTION

The ADL5544 is a single-ended RF/IF gain block amplifier that provides broadband operation from 30 MHz to 6 GHz. The ADL5544 provides over 34 dBm of OIP3 using only 55 mA from a 5 V supply.

The ADL5544 provides a gain of 17 dB, which is stable over frequency, temperature, power supply, and from device to device. The amplifier is offered in the industry-standard SOT-89 package and is internally matched to 50 Ω at the input and output, making the ADL5544 very easy to implement in a wide variety of applications. The only external components required are the input/output accoupling capacitors, power supply decoupling capacitors, and dc bias inductor.

The ADL5544 is fabricated on an InGaP HBT process and has a high ESD rating of ±1.5 kV (Class 1C). The ADL5544 is also fully specified for operation across the wide temperature range of −40°C to +105°C. A fully populated RoHS-compliant evaluation board is available.
