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 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.
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.
