GENERAL DESCRIPTION

The ADL5534 contains two independent broadband, fixed-gain,

linear amplifiers that operates at frequencies up to 500 MHz.

The device can be used in a wide variety of applications

including cellular, satellite, broadband, and instrumentation

equipment.

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

frequency, temperature, power supply and from device to

device. The ADL5534 is single-ended and internally matched

to 50 Ω. Only input/output ac-coupling capacitors, power

supply decoupling capacitors, and an external bias inductor is

required for operation for each channel.

The ADL5534 is fabricated on a GaAs HBT process, and has an

ESD rating of + 1 kV (Class 1C). The device is packaged in a 16-

lead 5mm x 5mm LFCSP that uses an exposed paddle for

excellent thermal impedance.

The ADL5534 consumes 90 mA per channel on a single +5 V

supply and is fully specified for operation from −40°C to

+85°C.

The ADL5531 is the 20 dB gain single-channel version, and

fully populated evaluation boards for each IFA are available.
