The LTC®5594 is a direct conversion quadrature demodula-
tor optimized for high linearity zero-IF and low-IF receiver
applications in the 300MHz to 9GHz frequency range.
The very wide IF bandwidth of more than 1GHz makes
the LTC5594 particularly suited for demodulation of very
wideband signals, especially in 5G fronthaul/backhaul
receiver applications. The outstanding dynamic range of
the LTC5594 makes the device suitable for demanding
infrastructure direct conversion applications. Proprietary
technology inside the LTC5594 provides the capability
to optimize OIP2 to 65dBm, and achieve image rejection
better than 60dB. The DC offset control function allows
nulling of the DC offset at the A/D converter input, thereby
optimizing the dynamic range of true zero-IF receivers that
use DC-coupled IF signal paths. The wideband RF and LO
input ports make it possible to cover all the major wireless
infrastructure frequency bands using a single device. The
IF outputs of the LTC5594 are designed to interface directly
with most common A/D converter input interfaces. The
high OIP3 and high conversion gain of the device eliminate
the need for additional amplifiers in the IF signal path.
