GENERAL DESCRIPTION
The ADL5602 is a broadband 20 dB linear amplifier that operates
at frequencies up to 4 GHz. The device can be used in a wide
variety of cellular, CATV, military, and instrumentation equipment.
The ADL5602 is fabricated on an InGaP 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 ADL5602 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
specifications simultaneously, across the entire 4 GHz
frequency range.
The ADL5602 consumes 89 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.
The ADL5602 provides a gain of 20 dB, which is stable over
frequency, temperature, power supply, and from device to
device. The device is internally matched to 50 Ω at the input
and output, making the ADL5602 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.

BASIC CONNECTIONS
The basic connections for operating the ADL5602 are shown in
Figure 16. Recommended components are listed in Table 5. The
input and output should be ac-coupled with appropriately sized
capacitors (device characterization was performed with 0.1 μF
capacitors). A 5 V dc bias is supplied to the amplifier through
the bias inductor connected to RFOUT (Pin 3). The bias voltage
should be decoupled using a 1 µF capacitor, a 1.2 nF capacitor,
and a 68 pF capacitor.

SOLDERING INFORMATION AND RECOMMENDED
PCB LAND PATTERN
Figure 17 shows the recommended land pattern for the ADL5602.
To minimize thermal impedance, the exposed paddle on the
package underside should be soldered down to a ground plane
along with Pin 2. If multiple ground layers exist, they should be
stitched together using vias. For more information on land
pattern design and layout, refer to the AN-772 Application
Note, A Design and Manufacturing Guide for the Lead Frame
Chip Scale Package (LFCSP).

The ADL5602 achieves an ACPR of −75 dBc at −5 dBm output,
at which point device noise and not distortion is beginning to
dominate the power in the adjacent channels. At an output
power of +5 dBm, ACPR is still very low at −61 dBc, making
the device particularly suitable for PA driver applications.

ACPR AT 5MHz CARRIER OFFSET (dBc)
Figure 18 shows a plot of adjacent channel power ratio (ACPR)
vs. POUT for the ADL5602. The signal type being used is a single
W-CDMA carrier (Test Model 1-64) at 2140 MHz. This signal is
generated by a very low ACPR source. ACPR is measured at the
output by a high dynamic range spectrum analyzer, which
incorporates an instrument noise correction function.
