The ADL5721 from Analog Devices is a high-linearity low noise amplifier that operates from 5.9 to 8.5 GHz. It has been developed for microwave radio link receiver designs and satellite communications. The LNA has a gain of 25 dB, noise figure of less than 1.7 dB, P1dB of greater than -10.6 dBm and OIP3 of greater than 4 dBm. Its unique design offers a single-ended 50 Ω input impedance and provides a 100 Ω balanced differential output that is ideal for driving differential downconverters and radio frequency (RF) sampling analog-to-digital converters (ADCs). This LNA uses a band switch feature to allow the input P1dB and noise figure to trade off for optimum system performance. It is available in a 8-lead, LFCSP microwave package that measures 2.00 mm × 2.00 mm.
