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 intermodulation 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.
The ADL5365 is fabricated using a BiCMOS high performance IC process. The device is available in a 5 mm × 5 mm, 20-lead LFCSP, and operates over a −40°C to +85°C temperature range. An evaluation board is also available.

Product Lifecycle Not Recommended for New Designs
This designates products ADI does not recommend broadly for new designs.
Evaluation Kits (1)
ADL5365-EVALZ is a fully populated, 4-layer, Rogers 3003-based evaluation board. It requires a 5 V/95 mA or 3.3 V/56 mA power supply for normal operation. The power supply should be connected to the clip leads labeled VPOS and GND. All signal ports are populated with edge-mounted SMA connectors. RF-IN is the input port for down-converting evaluation, and the output port for up-converting evaluation. LO1_IN and LO2_IN are input ports for local oscillators. LO1_IN is enabled when the LOSEL clip lead is logic low. LO2_IN is enabled when LOSEL is pulled to logic high. IF1-OUT is the output port for up-converting evaluation, and the input port for up-converting evaluation. Power down feature is available for power supply at or under 3.6 V.
Tools & Simulations
ADIsimPLL enables the rapid and reliable evaluation of new high performance PLL products from ADI. It is the most comprehensive PLL Synthesizer design and simulation tool available today. Simulations performed include all key non-linear effects that are significant in affecting PLL performance. ADIsimPLL removes at least one iteration from the design process, thereby speeding the design- to-market.
ADIsimRF is an easy-to-use RF signal chain calculator. Cascaded gain, noise, distortion and power consumption can be calculated, plotted and exported for signal chains with up to 50 stages. ADIsimRF also includes an extensive data base of device models for ADI’s RF and mixed signal components.

Recommended Single-Ended IF Gain Blocks
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
