AD8339 is a DC to 50MHz quad I/Q demodulator and phase shifter.
This handbook describes the AD8339, a quad integrated I/Q demodulator with 16 programmable phase‑select steps per channel (22.5° per step). It includes functional block diagrams, pin configurations, logic interface details, and typical performance characteristics for use in medical imaging, phased‑array radar, and adaptive antenna systems.
The document also lists absolute maximum ratings, supply requirements, and recommended evaluation board connections. An ordering guide and package dimensions are provided for the 6 mm × 6 mm 40‑lead LFCSP version.
