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 3d B at 900MHz. The integrated LO driver supports a 50-Ω input impedance with a low LO drive level, helping to minimize external ponent count. The single-ended 50-Ohm broadband RF port allows for easy interfacing to both active devices and passive filters. The RF input accepts input signals as large as 1.8Vpp or 9d Bm (re: 50 Ω) at P1d B. 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, the outputs may swing +/-2Vdiff. The AD8344 is fabricated on Analog Devices proprietary, high performance Si Ge IC process. The AD8344 is available in a 16 lead CSP package. It operates over a - 40°C to +85°C temperature range. An evaluation board is available. Rev. Pr G Information furnished by Analog Devices is believed to be accurate and reliable.
