GENERAL DESCRIPTION

The ADL5365 uses a highly linear, doubly balanced passive

mixer core along with integrated RF and LO balancing circuitry

to allow for single-ended operation. The ADL5365 incorporates

an RF balun, allowing for optimal performance over a 1200 MHz

to 2500 MHz RF input frequency range using low-side LO

injection for RF frequencies from 1700 MHz to 2500 MHz and

high-side injection for frequencies from 1200 MHz to 1700 MHz.

The balanced passive mixer arrangement provides good LO to

RF leakage, typically better than −30 dBm, and excellent inter-

modulation performance. The balanced mixer core also provides

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.

The ADL5365 provides two switched LO paths that can be used

in test driven development (TDD) applications where it is desirable

to rapidly switch between two local oscillators. LO current can be

externally set using a resistor to minimize dc current

commensurate with the desired level of performance. For low

voltage applications, the ADL5365 is capable of operation at

voltages down to 3.3 V with substantially reduced current. Under

low voltage operation, an additional logic pin is provided to power

down (<200 µA) the circuit when desired.
