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 input band LNAs are each packaged in a tiny, thermally enhanced, impedance and provides a 100 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 40C to +85C.
