THEORY OF OPERATION

The ADL5725 is a narrow-band, high performance, low noise

amplifier targeting microwave radio link receiver designs. The

monolithic SiGe design is optimized for microwave radio link

bands ranging from 17.7 GHz to 19.7 GHz.

The unique design of the ADL5725 offers a single-ended 50 Ω

input impedance via the INPT pin, and provides a 100 Ω

balanced differential output via the OUTP and OUTN pins.

This LNA is ideal for driving Analog Devices differential

downconverters and RF sampling ADCs.

The ADL5725 provides cost-effective noise figure performance

without requiring more expensive III-V compounds process

technology.

The ADL5725 is available in a 2.00 mm × 2.00 mm LFCSP package,

and operates over the temperature range of −40°C to +85°C.
