ADL5721 Data Sheet THEORY OF OPERATION
The ADL5721 is a narrow-band, high performance, low noise This LNA uses a band switch feature to al ow the input P1dB amplifier targeting microwave radio link receiver designs. The and noise figure to trade off for optimum system performance. monolithic SiGe design is optimized for microwave radio link The BAND pin al ows the user to select between two frequency bands ranging from 5.9 GHz to 8.5 GHz. ranges. A logic low of 0 V on the BAND pin selects the lower The unique design of the ADL5721 offers a single-ended 50 Ω frequency range from 5.9 GHz to 7.2 GHz, whereas a logic high input impedance and provides a 100 Ω balanced differential of 1.8 V selects the higher frequency range from 7.1 GHz to output. This LNA is ideal for driving Analog Devices differential 8.5 GHz. downconverters and RF sampling ADCs. The ADL5721 is available in an 8-lead, 2.00 mm × 2.00 mm The ADL5721 provides cost-effective noise figure performance LFCSP package, and operates over the temperature range of without requiring more expensive III-V compounds process −40°C to +85°C. technology.
