GENERAL DESCRIPTION
The ADL5602 is a broadband 20 dB linear amplifier that operates
at frequencies up to 4 GHz. The device can be used in a wide
variety of cellular, CATV, military, and instrumentation equipment.
The ADL5602 provides the highest dynamic range available
from an internally matched gain block. This is accomplished
by providing extremely low noise figures and very high OIP3
specifications simultaneously, across the entire 4 GHz
frequency range.
The ADL5602 provides a gain of 20 dB, which is stable over
frequency, temperature, power supply, and from device to
device. The device is internally matched to 50 Ω at the input
and output, making the ADL5602 very easy to implement in a
wide variety of applications. Only input/output ac coupling
capacitors, power supply decoupling capacitors, and an external
inductor are required for operation.

The ADL5602 is fabricated on an InGaP HBT process and has
an ESD rating of ±1.5 kV (Class 1C). The device is available in a
thermally efficient SOT-89 package.
The ADL5602 consumes 89 mA on a single 5 V supply and is
fully specified for operation from −40°C to +85°C.
A fully populated RoHS-compliant evaluation board is available.
