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 dB with a very high

OIP3 of over 38 dBm simultaneously, which delivers a high

dynamic range.

The ADL5611 provides a gain of 22 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 internally matched to 50 Ω at the input and

output, making the ADL5611 very easy to implement in a wide

variety of applications. The only external parts required are the

input/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 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.
