GENERAL DESCRIPTION
The ADL5724 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 12.7 GHz to 15.4 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 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.

Description
1 VCC1
1.8 V Power Supply. It is recommended to place the decoupling capacitors as close to this pin as possible.
2 GND
Ground.
3 INPT
RF Input. This is a 50 Ω single-ended input.
4 RBIAS
Resistor Bias. For typical operation, connect a 442 Ω resistor from RBIAS to GND. It is recommended to
place the RBIAS resistor as close to the pin as possible.
5 DNC
Do Not Connect. Do not connect to this pin.
6, 7
OUTP, OUTN
RF Outputs. These pins are 100 Ω differential outputs.
8 VCC2
3.3 V Power Supply. It is recommended to place the decoupling capacitors as close to this pin as possible.
EPAD (EP)
Exposed Pad. The exposed pad must be soldered to a low impedance ground plane.
