GENERAL DESCRIPTION

The ADL5611 is a single-ended RF/IF gain block amplifier that

provides broadband operation from 30 MHz to 6 GHz. The

ADL5611 provides a low noise figure of 2.1 dB with a very

high OIP3 of 40.0 dBm simultaneously, which delivers a high

dynamic range.

The ADL5611 provides a gain of 22.2 dB that is stable over

frequency, temperature, and 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 ADL5611 easy to implement in a wide variety of

applications.

The only external parts required are the input and output ac

coupling capacitors, power supply decoupling capacitors, and

bias inductor.

The ADL5611 has a high ESD rating of ±1.5 kV (Class 1C) and

is fully specified for operation across a wide temperature range

of −40°C to +105°C.

A fully populated RoHS compliant evaluation board is available.
