GENERAL DESCRIPTION

The ADL5534 contains two broadband, fixed-gain, linear

amplifiers in an 4x4 mm LFCSP package and operates 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.

The ADL5534 has a fixed gain 20 dB and is stable over

frequency, temperature, power supply and from device to

device. It achieves an OIP3 of 41.8 dBm with an output

compression point of +20.2 dBm and a noise figure of 2.5 dB.

The ADL5534 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.

This IF amplifier operates with supply voltage of +5V,

consuming 90 mA of supply current per amplifier.

Fabricated on a GaAs HBT process and has an ESD rating of

1000 V (Class 1C). The device is packaged in a 4mm x 4mm

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.
