GENERAL DESCRIPTION

The AD8344 is a highperformance, broadband activemixer.

It is well suited for demanding receive-channel applications that require wide bandwidth on all ports and very low inter modulation distortion and noise figure.

The AD8344 provides a typical conversiongain of4.5 dB at 890 MHz. The integrated LO driver supports a 50 ? input impedance witha low LO drive level, helping to minimize external component count.

The single-ended 50? roadband RF port allows for easy interfacing to both active devices and passive filters.

The RF input accepts input signals as large as 1.7 V p-p or8.5 dBm (re:50 ?) at P1dB.
