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.

Stresses at or above those listed under Absolute Maximum
Ratings may cause permanent damage to the product. This is a
stress rating only; functional operation of the product at these
or any other conditions above those indicated in the operational
section of this specification is not implied. Operation beyond
the maximum operating conditions for extended periods may
affect product reliability.

THEORY OF OPERATION
The basic connections for operating the ADL5530 are shown in
Figure 22. Recommended components are listed in Table 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.

Figure 22. Basic Connections
For operation down to 10 MHz, a larger biasing choke is
recommended (see Table 5) along with larger ac-coupling
capacitors. Figure 23 shows a plot of input return loss and gain
with the recommended components.

SOLDERING INFORMATION AND RECOMMENDED
PCB LAND PATTERN
Figure 24 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.
