ADL5324 is a half-watt RF driver amplifier operating from 400 MHz to 4000 MHz with 14.6 dB gain, 43.1 dBm OIP3, 29.1 dBm P1dB, 3.8 dB noise figure, dynamically adjustable bias, low power supply current, no external bias resistor, and is used in wireless infrastructure, automated test equipment and ISM/AMR applications
The ADL5324 RF driver amplifier operates from 400 MHz to 4 GHz and provides a gain of up to 14.6 dB at 2140 MHz. It features a dynamically adjustable bias circuit that allows OIP3 and P1dB performance to be tuned between 3.3 V and 5 V without an external bias resistor, enabling output power from 25 dBm to 29 dBm.
The device is supplied in a 3‑lead SOT‑89 package (RK‑3) rated for –40 °C to +105 °C operation. It offers low supply current (62 mA‑133 mA) and an ESD rating of +3 kV (Class 2). Typical applications include wireless infrastructure, automated test equipment, and ISM/AMR systems.
