The ADL5534 is a dual-channel IF amplifier from Analog Devices that operates from 20 MHz to 500 MHz. It has a fixed gain of 20 dB and is stable over frequency, temperature, and power supply variations.
The ADL5534 dual IF amplifier provides a fixed 20 dB gain across a 20 MHz‑500 MHz range. It is internally matched to 50 Ω, includes bias control, and requires only input/output coupling capacitors and a bias inductor for each channel. The device is fabricated in a GaAs HBT process and packaged in a 16‑lead 5 mm × 5 mm LFCSP with an exposed paddle for thermal management.
Key specifications include a 5 V single‑supply operation, 98 mA per amplifier current draw, 0.5 W power dissipation, and an operating temperature range of –40 °C to +85 °C. The datasheet provides detailed pin configurations, typical scattering parameters, absolute maximum ratings, and ordering information.
