GENERAL DESCRIPTION

The ADL5601 is a broadband, 15 dB linear amplifier that operates

at frequencies up to 4.0 GHz. The device can be used in a wide

variety of cellular, cable television (CATV), military, and instru-

mentation equipment.

The ADL5601 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 speci-

fications simultaneously, across the entire 4.0 GHz frequency range.

The ADL5601 provides a gain of 15 dB, which is stable over

frequency, temperature, and supply voltage, as well as from device

to device. The device is internally matched to 50 Ω at the input

and output, making the ADL5601 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 ADL5601 is fabricated on an InGaP heterojunction bipolar

transistor (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 ADL5601 consumes 83 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.
