The ADL5330 is a high performance, low power, single-ended or differential input/output 10 MHz to 3 GHz voltage-controlled amplifier/attenuator with a 60 dB gain control range. It is optimized for controlling output power and features high linearity and low noise.
The ADL5330 is a high‑performance voltage‑controlled variable gain amplifier/attenuator covering 10 MHz to 3 GHz. It offers a wide gain‑control range (‑34 dB to +22 dB at 900 MHz) with linear‑in‑dB control (≈20 mV/dB) and can be powered from a single 4.75 V‑5.25 V supply. The device features 50 Ω input and output impedances, single‑ended or differential operation, and a power‑down mode with low standby current.
The datasheet provides full electrical specifications, absolute maximum ratings, pin descriptions, typical performance curves, and an ordering guide for the 24‑lead LFCSP_VQ package. It also includes application notes for RF power control, IQ modulation interfacing, and evaluation board details.
