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 SOT89 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.
