GENERAL DESCRIPTION

The ADL5354 uses a highly linear, doubly balanced, passive mixer core along with integrated RF and local oscillator (LO) balancing circuitry to allow single-ended operation. The ADL5354 incor­porates the RF baluns, allowing for optimal performance over a 2200 MHz to 2700 MHz RF input frequency range. The balanced passive mixer arrangement provides good LO-to-RF leakage, typically better than −37 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. A high linearity IF buffer amplifier follows the passive mixer core to yield a typical power conversion gain of 8 dB and can be used with a wide range of output impedances.
The ADL5354 provides two switched LO paths that can be used in time division duplex (TDD) applications where it is desirable to ping-pong 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 ADL5354 is capable of operation at voltages as low as 3.3 V with substantially reduced current. For low voltage operation, an additional logic pin is provided to power down (~300 µA) the circuit when desired.
The ADL5354 is fabricated using a BiCMOS high performance IC process. The device is available in a 6 mm × 6 mm, 36-lead LFCSP and operates over a −40°C to +85°C temperature range. An evaluation board is also available.
