GENERAL DESCRIPTION

The ADL5530 is a broadband, fixed-gain, linear amplifier that

operates at frequencies up to 1000 MHz. The device can be used

in a wide variety of wired and wireless devices, including

cellular, broadband, CATV, and LMDS/MMDS applications.

The ADL5530 provides a gain of 16.5 dB, which is stable over

frequency, temperature, power supply, and from device to

device. It achieves an OIP3 of 37 dBm with an output

compression point of 21.8 dB and a noise figure of 3 dB.

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

with an input return loss of 11 dB. Only input/output

ac-coupling capacitors, a power supply decoupling capacitor,

and an external inductor are required for operation.

The ADL5530 operates with supply voltages of 3 V or 5 V with

a supply current of 110 mA.

The ADL5530 is fabricated on a GaAs pHEMPT process. The

device is packaged in a 3 mm × 2 mm LFCSP that uses an

exposed paddle for excellent thermal impedance. It operates

from −40°C to +85°C. A fully populated evaluation board is

also available.
