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 accoupling 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.
