ADL5391ACPZ-R7

ADL5391ACPZ-R7 is a DC to 2.0GHz multiplier. It draws on three decades of experience in advanced analogue multiplier products. It provides the same general mathematical function that has been field-proven to provide an exceptional degree of versatility in function synthesis. The most significant advance in the ADL5391 is the use of a new multiplier core architecture, which differs markedly from the conventional form that has been in use since 1970. The conventional structure that employs a current mode, translinear core is fundamentally asymmetric with respect to the X and Y inputs, leading to relative amplitude and timing misalignments that are problematic at high frequencies. Applications include wideband multiplication and summing, high frequency analogue modulation, adaptive antennas (diversity/phased array), square-law detectors and true rms detectors, accurate polynomial function synthesis, DC capable VGA with very fast control.
