The ADL5369 uses a highly linear, doubly balanced passive mixercore along with integrated radio frequency (RF) and local oscillator(LO) balancing circuitry to allow single-ended operation. TheADL5369 incorporates an RF balun, allowing optimal performanceover a 300 MHz to 1100 MHz RF input frequency range. Thebalanced passive mixer arrangement provides good LO to RFleakage, typically better than −25 dBm, and excellent intermodulationperformance. The balanced mixer core also providesextremely high input linearity, allowing the device to be usedin demanding cellular applications where in-band blocking signalsmay otherwise result in the degradation of dynamic performance.The passive mixer core yields a typical power conversionloss of 6.2 dB.

The ADL5369 provides two switched LO paths that can beused in time division duplex (TDD) applications where it isdesirable to rapidly switch between two local oscillators. LOcurrent can be externally set using a resistor to minimize dccurrent commensurate with the desired level of performance.For low voltage applications, the ADL5369 is capable of operationat voltages down to 3.3 V with substantially reduced current.Under low voltage operation, an additional logic pin is providedto power down (<200 μA) the circuit when desired.

The ADL5369 is fabricated using a BiCMOS high performanceIC process. The device is available in a 5 mm × 5 mm, 20-leadLFCSP and operates over a −40°C to +85°C temperature range.An evaluation board is also available.
