GENERAL DESCRIPTION The ADL5356 uses a highly linear, doubly balanced, passive mixer The ADL5356 provides two switched LO paths that can be used core along with integrated RF and local oscillator (LO) balancing in TDD applications where it is desirable to ping-pong between circuitry to allow single-ended operation. The ADL5356 two local oscillators. LO current can be externally set using a incorporates the RF baluns, allowing for optimal performance over resistor to minimize dc current commensurate with the desired a 1200 MHz to 2500 MHz RF input frequency range. Performance level of performance. For low voltage applications, the ADL5356 is is optimized for RF frequencies from 1700 MHz to 2500 MHz capable of operation at voltages down to 3.3 V with substantially using a low-side LO and RF frequencies from 1200 MHz to reduced current. Under low voltage operation, an additional logic pin is provided to power down (<300 A) the circuit when desired. 1700 MHz using a high-side LO. The balanced passive mixer arrangement provides good LO-to-RF leakage, typically better The ADL5356 is fabricated using a BiCMOS high performance than 35 dBm, and excellent intermodulation performance. The IC process. The device is available in a 6 mm 6 mm, 36-lead balanced mixer core also provides extremely high input linearity, LFCSP and operates over a 40C to +85C temperature range. allowing the device to be used in demanding cellular applications An evaluation board is also available. where in-band blocking signals may otherwise result in the degradation of dynamic performance.
