The ADL5801 utilizes a high linearity doubly balanced active
mixer core with integrated LO buffer amplifier to provide high
dynamic range frequency conversion from 10MHz to 6GHz.
The mixer benefits from a proprietary linearization architecture
which provides enhanced IP3 performance when subject to
high input levels. A bias adjust feature allows the input
linearity, SSB Noise Figure, and DC current to be optimized
using a single control pin. An optional input power detector is
provided for adaptive bias control. The high input linearity
allows the device to be used in demanding cellular applications
where in-band blocking signals may otherwise result in
degradation in dynamic performance. Employing the adaptive
bias feature allows the part to provide high IP3 performance
when presented with large blocking signals. When blockers are
removed the ADL5801 can automatically bias down to provide
low noise figure and low power consumption.
