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.
