ADL5357: 500 MHz至1700 MHz平衡混频器,内置LO缓冲、中频放大器和RF巴伦

ADL5357 功能框图ADL5357利用高度线性的双重平衡无源混频器内核以及集成式RF和LO平衡电路实现单端操作。该器件内置RF巴伦,可在500 MHz至1700 MHz RF输入频率范围内提供最佳性能。对于500 MHz至1100 MHz的RF频率,该器件使用高端LO注入;对于1100 MHz至1700 MHz的RF频率,该器件使用低端注入。(关于700 MHz至1100 MHz的RF频率时的低端注入,请联系ADI公司。)平衡无源混频器配置可提供良好的LO至RF泄漏(典型值优于-25 dBm)以及出色的交调性能。平衡混频器内核还能提供极高的输入线性度,使该器件能用在要求苛刻的蜂窝应用中。对于这些应用,如果输入线性度不高,带内阻塞信号可能会导致动态性能下降。无源混频器内核之后是高线性度中频缓冲放大器,它可提供典型值为8.5 dB的功率转换增益,并且可以与各种输出阻抗一起使用。(关于无中频放大器且具有更高IIP3的单通道混频器产品,请联系ADI公司。)

ADL5357提供两条开关LO路径,可用在需要两个本机振荡器之间进行乒乓式操作的TDD应用中。LO电流可以利用电阻在外部设置,使所需性能水平的相应直流电流最小。另外还提供一个逻辑引脚,用来在需要时使电路进入省电模式(< 200 µA)。ADL5357采用BiCMOS高性能IC工艺制造,提供5 mm x 5 mm、20引脚LFCSP封装,工作温度范围为−40°C至+85°C,同时提供评估板。

The ADL5357 utilizes a highly linear doubly balanced passive mixer core along with integrated RF and LO balancing circuitry to allow for single-ended operation. The ADL5357 incorporates an RF balun allowing for optimal performance over a 500 to 1700 MHz RF input frequency range using high-side LO injection for RF frequencies between 500 MHz to 1100 MHz, and low side injection for RF frequencies between 1100 MHz and 1700 MHz. (For low side injection at RF frequencies between 700 MHz and 1100 MHz, please contact the factory.) 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. A high linearity IF buffer amp follows the passive mixer core, to yield a typical power conversion gain of 8.5 dB, and can be utilized with a wide range of output impedances. (For a higher IIP3 version of the single mixer without the IF amplifiers, please contact the factory).

The ADL5357 provides two switched LO paths that can be utilized in 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. An additional logic pin is provided to power down (<100 µA) the circuit when desired.For low voltage applications, the ADL5357 is capable of operation at voltages down to 3.3V with substantially reduced current.The ADL5357 is fabricated using a BiCMOS high performance IC process. The device will be available in a 5 mm × 5 mm 20-lead LFCSP package and operates over a −40°C to +85°C temperature range. An evaluation board is also available.
