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.
