Matched 50 single-ended input Matched 100 differential outputs 8-lead, 2.00 mm 2.00 mm LFCSP microwave packaging APPLICATIONS Point to point microwave radios Instrumentation Satellite communications (SATCOM) Phased arrays GENERAL DESCRIPTION The ADL5721 is a narrow-band, high performance, low noise performance that, in the past, required more expensive three- amplifier targeting microwave radio link receiver designs. The five (III-V) compounds process technology to achieve. This monolithic silicon germanium (SiGe) design is optimized for LNA uses a band switch feature to allow the input P1dB and microwave radio link bands ranging from 5.9 GHz to 8.5 GHz. noise figure to trade off for optimum system performance. The unique design offers a single-ended 50 input impedance The ADL5721 and ADL5723 to ADL5726 family of narrow- and provides a 100 balanced differential output that is ideal band LNAs are each packaged in a tiny, thermally enhanced, for driving Analog Devices, Inc., differential downconverters 2.00 mm 2.00 mm LFCSP package. The ADL5721 and and radio frequency (RF) sampling analog-to-digital converters ADL5723 to ADL5726 family operates over the temperature (ADCs). This low noise amplifier (LNA) provides noise figure range of 40C to +85C. Rev. 0 Document Feedback Information furnished by Analog Devices is believed to be accurate and reliable.
