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 accoupling 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.
