AD8344 General Description

    The AD8344 is a high performance, broadband active mixer. It is well suited for demanding receive-channel applications that require wide bandwidth on all ports and very low intermodulation distortion and noise figure.

    The AD8344 provides a typical conversion gain of 4.5 dB at 890 MHz. The integrated LO driver supports a 50 input impedance with a low LO drive level, helping to minimize external component count.

    The single-ended 50 broadband 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 or 8.5 dBm (re: 50 ) at P1dB.

    The open-collector differential outputs provide excellent balance and can be used with a differential filter or IF amplifier, such as the AD8369 or AD8351. These outputs may also be converted to a single-ended signal through the use of a matching network or a transformer (balun). When centered on the VPOS supply voltage, each of the differential outputs may swing 2.5 V p-p.

    The AD8344 is fabricated on an Analog Devices proprietary, high performance SiGe IC process. The AD8344 is available in a 16-lead LFCSP package. It operates over a -40 to +85 temperature range. An evaluation board is also available.
