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.
