GENERAL DESCRIPTION
The ADL5536 is a 20 dB linear amplifier that operates at
frequencies up to 1 GHz. The device can be used in a wide
variety of cellular, CATV, military, and instrumentation
equipment.
The ADL5536 provides the highest dynamic range available
from an internally matched IF gain block. This is accomplished
by providing extremely low noise figures and very high OIP3
specifications simultaneously across the entire 1 GHz frequency
range. The ADL5536 also provides extremely flat gain and P1dB
over frequency, which are stable over temperature, power supply,
and from device to device.
The device is internally matched to 50 at the input and output,
making the ADL5536 very easy to implement in a wide variety
of applications. Only input/output ac coupling capacitors, power
supply decoupling capacitors, and an external inductor are
required for operation.

The ADL5536 is fabricated on a GaAs HBT process and has an
ESD rating of ±2 kV (Class 2). The device is assembled in an
MSL-1 rated SOT-89 package that uses an exposed paddle for
excellent thermal impedance.
The ADL5536 consumes only 105 mA on a single 5 V supply
and is fully specified for operation from −40°C to +85°C.
The ADL5536 is also pin-compatible with the 16 dB gain
ADL5535. Fully populated evaluation boards are available
for each amplifier.
