GENERAL DESCRIPTION
The ADL5531 is a broadband, fixed-gain, linear amplifier that
operates at frequencies up to 500 MHz. The device can be used
in a wide variety of equipment, including cellular, satellite,
broadband, and instrumentation equipment.
The ADL5531 provides a gain of 20 dB, which is stable over
frequency, temperature, power supply, and from device to device.
This amplifier is single-ended and internally matched to 50 Ω.
Only input/output ac coupling capacitors, power supply decoupling
capacitors, and external inductors are required for operation.

The ADL5531 is fabricated on a GaAs HBT process and has an
ESD rating of ±2 kV (Class 2). The device is packaged in an 8-lead
3 mm × 3 mm LFCSP that uses an exposed paddle for excellent
thermal impedance.
The ADL5531 consumes 100 mA on a single 5 V supply and is
fully specified for operation from −40°C to +85°C.
The 15 dB gain version, ADL5532, and the dual-channel 20 dB
gain version, ADL5534, are also available.
