GENERAL DESCRIPTION
The ADL5533 is a fixed-gain, linear amplifier that operates at
frequencies up to 1000 MHz. Intended for use in a wide variety
of applications, including broadband, CATV, cable modem and
FTTH.
The fixed gain of 20 dB is stable over frequency, temperature,
power supply and from device to device. OIP3 is +37.3 dBm
with an output compression point of +18.8 dBm and a noise
figure of 2.9 dB.
The ADL5533 is single-ended and internally matched to 75 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.
This amplifier operates with a supply voltage of +5V, consuming
66 mA of supply current.
The ADL5533, 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.
