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 fixed.
The ADL5531 is a GaAs HBT broadband linear amplifier offering a fixed 20 dB gain from 20 MHz to 500 MHz. It is internally matched to 50 Ω, requires only AC‑coupling capacitors and external inductors, and consumes 100 mA from a single 5 V supply. The device is rated for operation from –40 °C to +85 °C and includes a +2 kV ESD protection.
The amplifier is packaged in an 8‑lead 3 mm × 3 mm LFCSP with an exposed paddle for thermal management. Detailed specifications include gain, output compression, third‑order intercept, noise figure, and power ratings, along with pin configurations and typical performance graphs.
