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 Ω 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.
