GENERAL DESCRIPTION
The ADL5724 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 12.7 GHz to 15.4 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.
