GENERAL DESCRIPTION
The ADL5545 is a single-ended RF/IF gain block amplifier
that provides broadband operation from 30 MHz to 6 GHz.
The ADL5545 provides over 36 dBm of OIP3 using only 56 mA
from a 5 V supply.
The ADL5545 provides a gain of 24 dB, which is stable over
frequency, temperature, power supply, and from device to device.
The amplifier is offered in the industry-standard SOT-89 package
and is internally matched to 50 Ω at the input and output, making
the ADL5545 very easy to implement in a wide variety of applications. The only external components required are the input/output
ac coupling capacitors, power supply decoupling capacitors, and
dc bias inductor.
Rev. A
The ADL5545 is fabricated on an InGaP HBT process and has
a high ESD rating of ±1.5 kV (Class 1C). The ADL5545 is also
fully specified for operation across the wide temperature range of
−40°C to +105°C. A fully populated RoHS-compliant evaluation
board is available.

A 5 V dc bias is supplied to the amplifier through the bias
inductor connected to RFOUT (Pin 3). The bias voltage must
be decoupled using 100 pF, 1 nF, and 10 µF power supply
decoupling capacitors. The typical current consumption for
the ADL5545 is 56 mA.
At low and high frequencies, the device exhibits improved
performance with the suggested setup configuration listed in
Table 6. Figure 30 to Figure 33 provide a comparison of the
performance of the device at the 100 MHz to 500 MHz and
4 GHz to 6 GHz bands when driven with the optimal setup
configuration and the default setup configuration.

Figure 29 shows the basic connections for operating the
ADL5545. The device supports operation from 30 MHz to 6 GHz.
However, for optimal performance at lower and higher frequency
bands, the board configuration must be adjusted. Table 6 lists
the recommended board configuration to operate the device at
various frequency bands.

Figure 34. Recommended Land Pattern
The land pattern on the ADL5545 evaluation board provides a
measured thermal resistance (θJA) of 53°C/W. To measure θJA,
the temperature at the top of the SOT-89 package is found with
an IR temperature gun. Thermal simulation suggests a junction
temperature 10°C higher than the top-of-package temperature.
With additional measurements of the ambient temperature and
I/O power, θJA can be determined.

OPERATION DOWN TO 30 MHz
To operate the ADL5545 at frequencies below 100 MHz, a feedback network must be implemented between the input and output
ports of the device to ensure stability. Figure 35 shows a sample
configuration used to evaluate the device at frequencies below
100 MHz. Figure 36 to Figure 38 demonstrate the performance
of the device in this configuration.

Figure 39 shows a plot of the adjacent channel power ratio
(ACPR) vs. POUT for the ADL5545. The signal type used is a
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 ADL5545 achieves an ACPR of −79 dBc at an output power
level of −4 dBm, at which point device noise and not distortion
begins to dominate the power in the adjacent channels. At an
output power level of 0 dBm, ACPR is still very low at −69 dBc.
