GENERAL DESCRIPTION
The ADL5531 is a broadband, fixed-gain, linear amplifier
that operates at frequencies up to 500 MHz. The device can be
used in a wide variety of equipment, including cellular, satellite,
broadband, and instrumentation equipment.
The ADL5531 is fabricated on a GaAs HBT process and has
an ESD rating of 2 ꢀk ꢁ(lass 2). The device is pacꢀaged in an
8-lead 3 mm × 3 mm LF(SP that uses an exposed paddle for
excellent thermal impedance.
The ADL5531 provides a gain of 20 dB, which is stable over
frequency, temperature, power supply, and from device to device.
This amplifier is single ended and internally matched to 50 Ω.
Only input/output ac coupling capacitors, power supply decoupling
capacitors, and external inductors are required for operation.
The ADL5531 consumes 100 mA on a single 5 k supply and is
fully specified for operation from −40°( to +85°(.
The dual-channel 20 dB gain version, ADL5534, is also available
from Analog Devices, Inc.

BASIC CONNECTIONS
2.03mm
The basic connections for operating the ADL5531 are shown
in Figure 16. The input and output are ac-coupled with 10 nF
(0402) capacitors. DC bias is provided to the amplifier via an
inductor (Coilcraft 1008CS-471XJLC or equivalent) connected
to the RFOUT pin. The bias voltage should be decoupled using
10 nF and 1 μF capacitors.

SOLDERING INFORMATION AND RECOMMENDED
PCB LAND PATTERN

5
1.53mm
0.71mm
Figure 15 shows the recommended land pattern for ADL5531.
To minimize thermal impedance, the exposed pad on the
package underside is soldered down to a ground plane. If
multiple ground layers exist, they are stitched together using
vias (a minimum of five vias is recommended). Pin 1, Pin 3,
Pin 4, Pin 6, and Pin 8 can be left unconnected or can be connected
to ground. Connecting these pins to ground slightly enhances
thermal impedance. For more information on land pattern design
and layout, refer to AN-772 Application Note, A Design and
Manufacturing Guide for the Lead Frame Chip Scale Package (LFCSP).
