GENERAL DESCRIPTION

The ADL5532 is a broadband, fixed-gain, linear amplifier that

operate at frequencies up to 500 MHz. The device can be used

in a wide variety of wired and wireless devices including

cellular, GSM and WCDMA, and broadband applications.

Gain is stable over frequency, temperature, power supply and

from device to device. The ADL553

2 achieves an OIP3 of 39.1

dBm with an output compression point of +19.9 dBm and a

noise figure of 3.0 dB.

This amplifier is single-ended and internally matched to 50 Ω

with an input return loss of 10 dB. Only input/output ac-

coupling capacitors, a power supply decoupling capacitor and

external inductor are required for operation.

The amplifier operates with a 5 V supply consuming 95 mA of

current.

The ADL5532 is fabricated on a GaAs HBT process and has an

ESD rating of 1000 V (Class 1C). The device is packaged in a 3mm

x 3mm LFCSP that uses an exposed paddle for excellent

thermal impedance and operates from −40°C to +85°C. A fully

populated evaluation board is available.
