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.
