Hot-selling and scarce AD8344ACPZ Active Receive Mixer 400 MHz to 1.2 GHz LFCSP16 spot stock

Product Descriptions

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 at890 MHz.The integrated LO driver supports a 50 Ω input impedance with a low LO drive level,helping to minimize external component count.

The single-ended 50 Ω 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 Ω) 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°C to +85°C temperature range.An evaluation board is also available.
