GENERAL DESCRIPTION
The ADL5723 is a narrow-band, high performance, low noise
amplifier (LNA) targeting microwave radio link receiver designs.
The monolithic silicon germanium (SiGe) design is optimized for
microwave radio link bands ranging from 10.1 GHz to 11.7 GHz.
The unique design offers a single-ended 50 Ω input impedance
and provides a 100 Ω balanced differential output that is ideal
for driving Analog Devices, Inc., differential downconverters
and radio frequency (RF) sampling analog-to-digital converters
(ADCs). This LNA provides noise figure performance that, in
the past, required more expensive three-five (III-V) compounds
process technology to achieve.
The ADL5721 and ADL5723 to ADL5726 family of narrow-band
LNAs are each packaged in a tiny, thermally enhanced, 2.00 mm ×
2.00 mm LFCSP package. The ADL5721 and ADL5723 to
ADL5726 family operates over the temperature range of −40°C
to +85°C.

THEORY OF OPERATION
The ADL5723 is a narrow-band, high performance, low noise
amplifier targeting microwave radio link receiver designs. The
monolithic SiGe design is optimized for microwave radio link
bands ranging from 10.1 GHz to 11.7 GHz.
This LNA is ideal for driving Analog Devices differential
downconverters and RF sampling ADCs.
The ADL5723 provides cost-effective noise figure performance
without requiring more expensive III-V compounds process
technology.
The unique design of the ADL5723 offers a single-ended 50 Ω
input impedance via the INPT pin, and provides a 100 Ω
balanced differential output via the OUTP and OUTN pins.
The ADL5723 is available in a 2.00 mm × 2.00 mm LFCSP package,
and operates over the temperature range of −40°C to +85°C.

LAYOUT
Solder the exposed pad on the underside of the ADL5723 to a
low thermal and electrical impedance ground plane. This pad is
typically soldered to an exposed opening in the solder mask on
the evaluation board. Connect the ground vias to all other
ground layers on the evaluation board to maximize heat
dissipation from the device package.

DIFFERENTIAL vs. SINGLE-ENDED OUTPUT
–5
This section provides the test results that compare the ADL5723
using a differential vs. a single-ended output. When using the
device as a single-ended output, use the RFOP output on the
evaluation board and terminate RFON to 50 Ω. Note that the
converse can be done as well; however, doing so produces
slightly different results from the plots shown in this section
because there is some amplitude imbalance between the two
differential ports, RFOP and RFON. The output trace and
connector loss were not deembedded for these measurements.

EVALUATION BOARD
The ADL5723-EVALZ comes with an ADL5723 chip. It supports
a single 5 V supply for ease of use. For 5 V operation, use the
3.3 V and 1.8 V test loops for evaluation purposes only. When
using a 3.3 V or 1.8 V supply, remove the R1 and R2 resistors
from the evaluation board. Figure 19 shows the ADL5723-
EVALZ evaluation board lab bench setup.
RESULTS
Figure 18 shows the expected results when testing the
ADL5723-EVALZ using the Rev. A version of the evaluation
board and its software. Note that future iterations of the software
may produce different results. See the ADL5723 product page
for the most recent software version.
INITIAL SETUP
Figure 18 shows the results of the differential output for an input
of 10.1 GHz at −15 dBm. The hybrid and board loss have not
been deembedded.
To set up the ADL5723-EVALZ, take the following steps:
1. Power up the ADL5723-EVALZ with a 5 V dc supply. The
supply current of the evaluation board is approximately
111 mA, which is a combination of the VCC1 (1.8 V) and
the VCC2 (3.3 V) currents.
2. Connect the signal generator to the input of the ADL5723-
EVALZ.
3. Connect RFOP and RFON to a 180° hybrid that works
within the 10.1 GHz to 11.7 GHz frequency range.
4. Connect the difference output of the hybrid to the
spectrum analyzer. The sum port of the hybrid must be
terminated to 50 Ω.
