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.
