MAX2045/MAX2046/MAX2047 low-cost, fully integrated vector multipliers alter the magnitude and phase of an RF signal.
The MAX2045, MAX2046, and MAX2047 are low‑cost, fully integrated vector multipliers that adjust the magnitude and phase of RF signals. Each device is optimized for a specific frequency band (UMTS, DCS/PCS, or GSM) and features differential RF inputs and outputs, as well as an internal 2.5 V reference for single‑ended voltage‑mode operation.
These devices operate from a 4.75 V to 5.25 V single supply and are offered in a compact 5 mm × 5 mm, 32‑lead thin QFN package. Key specifications include ±0.2 dB gain flatness, ±1° phase flatness, 800 mW power consumption, and a continuous 360° phase control range. Applications include base‑station feed‑forward and predistortion amplifiers, RF magnitude/phase adjustment, RF cancellation loops, and beam‑forming systems.
