The ADL5358 utilizes two highly linear doubly balanced passive
mixer cores along with integrated RF and LO balancing
circuitry to enable single-ended operation. The ADL5358
incorporates two RF baluns allowing for optimal main and
diversity mixer performance over a 500 to 1700 MHz RF input
frequency range using high-side LO injection for RF
frequencies between 500MHz to 1100MHz, and low side
injection for RF frequencies between 1100MHz and 1700MHz.
(For low side injection at RF Frequencies between 700MHz and
1100 MHz, please contact the factory.) The balanced passive
mixer arrangement provides good LO to RF leakage, typically
better than -25dBm, and excellent intermodulation
performance. The balanced mixer cores also provide extremely
high input linearity allowing the device to be used in
demanding cellular applications where in-band blocking signals
may otherwise result in the degradation of dynamic
performance. A high linearity IF buffer amps follow the passive
mixer cores, to yield a typical power conversion gain of 8.5dB,
and can be utilized with a wide range of output impedances.
(For a higher IIP3 version of the dual mixer without the IF
amplifiers, please contact the factory).
