AD8343 is a high-performance broadband active mixer. With wide bandwidth on all ports and very low intermodulation distortion, this device is well suited for demanding transmit applications or receive channel applications. It provides a typical conversion gain of 7dB. The integrated LO driver supports a 50 ohm 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 cantered on the VPOS supply voltage, the outputs swing ±1V. It is used in applications such as cellular base stations, wireless LAN, satellite converters, SONET/SDH radio, radio links, RF instrumentation.
