The ADL5726 is a narrow-band, high performance, low noise digital converters (ADCs). This LNA provides noise figure amplifier (LNA) targeting microwave radio link receiver performance that, in the past, required more expensive three- designs. The monolithic silicon germanium (SiGe) design is five (III-V) compounds process technology to achieve. optimized for microwave radio link bands ranging from 21.2 GHz The ADL5721 and ADL5723 to ADL5726 family of narrow- to 23.6 GHz. The unique design offers a single-ended 50 Ω input band LNAs are each packaged in a tiny, thermally enhanced, impedance and provides a 100 Ω balanced differential output 2.00 mm × 2.00 mm LFCSP package. The ADL5721 and that is ideal for driving Analog Devices, Inc., differential ADL5723 to ADL5726 family operates over the temperature downconverters and radio frequency (RF) sampling analog-to- range of −40°C to +85°C.
