AD8343是一款高性能、宽带有源混频器,具有极低交调失真,所有端口均具有宽带宽,非常适合要求严格的发射应用或接收通道应用。AD8343的典型变频增益为7 dB。集成的LO驱动器以低LO驱动电平,支持50 Ω差分输入阻抗,有助于将外部元件数降至最少。开发差分输入可以直接与差分滤波器接口,或通过平衡-不平衡变换器(变压器)驱动,由单端源提供平衡驱动。开集差分输出可以用来驱动差分中频信号接口,或通过匹配网络或变压器转换为单端信号。以VPOS电源电压为中心时,输出摆幅为±1 V。LO驱动器电路的典型功耗为15 mA。可利用两个外部电阻来设置混频器内核电流,以达到要求的性能,总电流为20 mA至60 mA。采用5 V单电源供电时,相应的功耗为100 mW至300 mW。AD8343采用ADI公司的高性能25 GHz硅双极性IC工艺制造,提供14引脚TSSOP封装,工作温度范围为−40°C至+85°C,同时提供配置齐全的评估板。
The AD8343 is a high-performance broadband active mixer. With wide bandwidth on all ports and very low intermodulation distortion, the AD8343 is well suited for demanding transmit applications or receive channel applications.The AD8343 provides a typical conversion gain of 7 dB. The integrated LO driver supports a 50 Ω differential input impedance with low LO drive level, helping to minimize external component count.The open-emitter differential inputs can be interfaced directly to a differential filter or driven through a balun (transformer) to provide a balanced drive from a single-ended source.
The open-collector differential outputs can be used to drive a differential IF signal interface or convert to a single-ended signal through the use of a matching network or transformer. When centered on the VPOS supply voltage, the outputs swing ±1 V.The LO driver circuitry typically consumes 15 mA of current. Two external resistors are used to set the mixer core current for required performance, resulting in a total current of 20 mA to 60 mA. This corresponds to power consumption of 100 mW to 300 mW with a single 5 V supply.The AD8343 is fabricated on Analog Devices, Inc.’s high-performance 25 GHz silicon bipolar IC process. The AD8343 is available in a 14-lead TSSOP package. It operates over a −40°C to +85°C temperature range. A device-populated evaluation board is available.
