300 MHz to 1100 MHz Balanced Mixer, LO Buffer and RF Balun
The ADL5369 uses a highly linear, doubly balanced passive mixer core along with integrated radio frequency (RF) and local oscillator (LO) balancing circuitry to allow single-ended operation. The ADL5369 incorporates an RF balun, allowing optimal performance over a 300 MHz to 1100 MHz RF input frequency range. The balanced passive mixer arrangement provides good LO to RF leakage, typically better than −25 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 passive mixer core yields a typical power conversion loss of 6.2 dB.
The ADL5369 provides two switched LO paths that can be used in time division duplex (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 ADL5369 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 ADL5369 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.

This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
ADL5369-EVALZ is a fully populated, 4-layer, Rogers 3003-based evaluation board. It requires a 5 V/84 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.
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.
