GENERAL DESCRIPTION
The ADL5721 is a narrow-band, high performance, low noise
amplifier targeting microwave radio link receiver designs. The
monolithic silicon germanium (SiGe) design is optimized for
microwave radio link bands ranging from 5.9 GHz to 8.5 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 low noise amplifier (LNA) provides noise figure
performance that, in the past, required more expensive three-
five (III-V) compounds process technology to achieve. This
LNA uses a band switch feature to allow the input P1dB and
noise figure to trade off for optimum system performance.
The ADL5721 and ADL5723 to ADL5726 family of narrow-
band LNAs are each packaged in a tiny, thermally enhanced,
2.00 mm × 2.00 mm LFCSP package. The ADL5721 and
ADL5723 to ADL5726 family operates over the temperature
range of −40°C to +85°C.

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