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 instrumentation 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 specifications 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
RF/IF Gain Block

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.

BASIC CONNECTIONS
The basic connections for operating the ADL5601 are shown in
Figure 15. Recommended components are listed in Tabl e 5. The
input and output should be ac-coupled with appropriately sized
capacitors (the device characterization was performed with
0.1 F 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 16 shows the recommended land pattern for the ADL5601.
To minimize thermal impedance, the exposed paddle on the
package underside, along with Pin 2, should be soldered to a
ground plane. 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).

W-CDMA ACPR PERFORMANCE
Figure 17 shows a plot of the adjacent channel power ratio
(ACPR) vs. P
single wideband code division multiple access (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 that incorporates an
instrument noise-correction function.
The ADL5601 achieves an ACPR of −69 dBc at −5 dBm output,
at which point device noise, rather than distortion, begins to
dominate the power in the adjacent channels. At an output
power of +5 dBm, ACPR is still very low at −56 dBc, making
the device particularly suitable for power amplifier (PA) driver
applications.
