GENERAL DESCRIPTION
The ADL5726 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 21.2 GHz
to 23.6 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.

The ADL5726 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

This LNA is ideal for driving Analog Devices differential

The ADL5726 provides cost-effective noise figure performance
without requiring more expensive III-V compounds process

The unique design of the ADL5726 offers a single-ended 50 Ω

LAYOUT
Solder the exposed pad on the underside of the ADL5726 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 resultsthat compare the ADL5726
using a differential vs. single-ended output. When using the
device as a single-ended output, use the RFOP output of 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.

This section provides the test results at a higher frequency from
23.2 GHz to 26.5 GHz. Differential outputs are measured here.
Traces, hybrids, and connector losses were deembeded for all

EVALUATION BOARD
The ADL5726-EVALZ comes with an ADL5726 chip. It supports
a single 5 V supply for ease of use. For 5 V operation, the 3.3 V
and 1.8 V test loops are 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 25 shows the ADL5726-
EVALZ lab bench setup.
RESULTS
Figure 24 shows the expected results when testing the
ADL5726-EVALZ using the Rev. A version of the evaluation
board and its software. Note that future iterationsof the software
may produce different results. See the ADL5726 product page
for the most recent software version.
INITIAL SETUP
Figure 24 shows the results of the differential output for an input
of 21.2 GHz at −15 dBm. The hybrid and board loss have not
been deembedded.
To set up the ADL5726-EVALZ, take the following steps:
1. Power up the ADL5726-EVALZ with a 5 V dc supply. The
supply current of the evaluation board is approximately
90 mA, which is a combination of the VCC1 (1.8 V) and
the VCC2 (3.3 V) currents.
2. Connect the signal generatorto the input of the ADL5726-
EVALZ.
3. Connect RFOP and RFON to a 180° hybrid that works
within the 21.2 GHz to 23.6 GHz frequency range.
4. Connect the difference output of the hybrid to the
