GENERAL DESCRIPTION

The ADL5360 utilizes two highly linear doubly balanced passive

mixer cores along with integrated RF and LO balancing

circuitry to enable single-ended operation. The ADL5360

incorporates two RF baluns allowing for optimal main and

diversity mixer performance over a 700 to 1000 MHz RF input

frequency range using low-side LO injection. 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. High linearity IF buffer amps follow the passive

mixer cores, to yield a typical power conversion gain of 9.5dB.

(For a higher IIP3 version of the dual mixer without the IF

amplifiers, please contact the factory).

The ADL5360 provides two switched LO paths that can be

utilized in TDD applications where it is desirable to rapidly

alternate between two local oscillators. LO current can be

externally set using a resistor to minimize DC current

commensurate with the desired level of performance. An

additional 3V logic pin is provided to power down (<100uA)

the circuit when desired.

For low voltage applications, the ADL5360 is capable of

operation at voltages down to 3V with substantially reduced DC

current.

The ADL5360 is fabricated using a BiCMOS high performance

IC process. The device is available in a 6mm x 6mm 36-lead

LFCSP package and operates over a −40°C to +85°C

temperature range. An evaluation board is also available.
