GENERAL DESCRIPTION

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.
