The AD8343 is a high-performance broadband active mixer. With wide bandwidth on all ports and very low intermodula-tion 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 imped-ance 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.
