GENERAL DESCRIPTION
The ADL5530 is a broadband, fixed-gain, linear amplifier that
operates at frequencies up to 1000 MHz. The device can be used
in a wide variety of wired and wireless devices, including
cellular, broadband, CATV, and LMDS/MMDS applications.
The ADL5530 provides a gain of 16.5 dB, which is stable over
frequency, temperature, power supply, and from device to
device. It achieves an OIP3 of 37 dBm with an output
compression point of 21.8 dB and a noise figure of 3 dB.
This amplifier is single-ended and internally matched to 50 Ω
with an input return loss of 11 dB. Only input/output
ac-coupling capacitors, a power supply decoupling capacitor,
and an external inductor are required for operation.

The ADL5530 operates with supply voltages of 3 V or 5 V with
a supply current of 110 mA.
The ADL5530 is fabricated on a GaAs pHEMPT process. The
device is packaged in a 3 mm × 2 mm LFCSP that uses an
exposed paddle for excellent thermal impedance. It operates
from −40°C to +85°C. A fully populated evaluation board is
also available.

ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulates on
the human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high-energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.
Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.

THEORY OF OPERATION
The basic connections for operating the ADL5530 are shown in
Figure 21. Recommended components are listed in Tabl e 5. The
inputs and outputs should be ac coupled with appropriately
sized capacitors (device characterization was performed with
10 nF capacitors). DC bias is provided to the amplifier via an
inductor connected to the RF output pin. The bias voltage
should be decoupled using a 10 nF capacitor.
A bias voltage of 5 V is recommended. However, the device is
specified to operate down to 3 V with a slightly reduced
compression point and a reduced noise figure.

SOLDERING INFORMATION AND RECOMMENDED PCB LAND PATTERN
Figure 23 shows the recommended land pattern for ADL5530.
To minimize thermal impedance, the exposed paddle on the
package underside should be soldered down to a ground plane
along with Pin 8. If multiple ground layers exist, they should be
stitched together using vias. Pin 1, Pin 3, Pin 4, Pin 5 and Pin 6
can be left unconnected, or can be connected to ground.
Connecting these pins to ground slightly enhances thermal
impedance.

EVALUATION BOARD
Figure 24 shows the schematic for the ADL5530 evaluation
board. The board is powered by a single supply (between 3 V
and 5 V).
The components used on the board are listed in
Tabl e 6. Power
can be applied to the board through clip-on leads (J5, J6),
through an edge connector (P1), or through Jumper W1. Note
that IN2, OUT2, T1, T2, C6, C7 and C10 have no function.
Because Pin 1, Pin 3 and Pin 6 of ADL5530 are No Connects,
these pins are grounded on this PCB (this has no effect on
electrical performance).
