DO NOT CONNECT TO THIS PIN. Figure 1. GENERAL DESCRIPTION The ADL5723 is a narrow-band, high performance, low noise amplifier (LNA) targeting microwave radio link receiver designs. The monolithic silicon germanium (SiGe) design is optimized for microwave radio link bands ranging from 10.1 GHz to 11.7 GHz. The unique design offers a single-ended 50 Ω input impedance and provides a 100 Ω balanced differential output that is ideal for driving Analog Devices, Inc., differential downconverters and radio frequency (RF) sampling analog-to-digital converters (ADCs). This LNA provides noise figure performance that, in the past, required more expensive three-five (III-V) compounds process technology to achieve. The ADL5721 and ADL5723 to ADL5726 family of narrow-band LNAs are each pa...
