GENERAL DESCRIPTION

The ADL5545 is a single-ended RF/IF gain block amplifier

that provides broadband operation from 30 MHz to 6 GHz.

The ADL5545 provides over 36 dBm of OIP3 using only 56 mA

from a 5 V supply.

The ADL5545 provides a gain of 24 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 ADL5545 very easy to implement in a wide variety of applica-

tions. The only external components required are the input/output

ac coupling capacitors, power supply decoupling capacitors, and

dc bias inductor.

The ADL5545 is fabricated on an InGaP HBT process and has

a high ESD rating of ±1.5 kV (Class 1C). The ADL5545 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.
