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.

PERFORMANCE UP TO 26.5 GHz
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
measurements except output return loss. It is important to note
that this performance is typical and not guaranteed.
