The ADL5725 is a narrow-band, high performance, low noise This low noise amplifier provides noise figure performance that, in amplifier (LNA) targeting microwave radio link receiver designs. the past, required more expensive three-five (III-V) compounds The monolithic silicon germanium (SiGe) design is optimized for process technology to achieve. microwave radio link bands ranging from 17.7 GHz to 19.7 GHz. The ADL5721 and ADL5723 to ADL5726 family of narrow-band The unique design offers a single-ended 50 Ω input impedance LNAs are each packaged in a tiny, thermal y enhanced, 2.00 mm × and provides a 100 Ω balanced differential output that is ideal for 2 mm LFCSP package. The ADL5721 and ADL5723 to ADL5726 driving Analog Devices, Inc., differential downconverters and radio family operates over the temperature range of −40°C to +85°C. frequency (RF) sampling analog-to-digital converters (ADCs).
