The monolithic silicon germanium (SiGe) design is optimized for The ADL5721 and ADL5723 to ADL5726 family of narrow- microwave radio link bands ranging from 12.7 GHz to 15.4 GHz. band LNAs are each packaged in a tiny, thermally enhanced, The unique design offers a single-ended 50 input impedance 2.00 mm 2.00 mm LFCSP package. The ADL5721 and and provides a 100 balanced differential output that is ideal ADL5723 to ADL5726 family operates over the temperature for driving Analog Devices, Inc., differential downconverters range of 40C to +85C. and radio frequency (RF) sampling analog-to-digital converters (ADCs). This LNA provides noise figure performance that, in Rev. 0 Document Feedback Information furnished by Analog Devices is believed to be accurate and reliable.
