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 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.

Markets and Technologies
Product Lifecycle Recommended for New Designs
This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
Evaluation Kits (1)
AD8344-EVAL is a fully populated, 4-layer, FR4-based evaluation board. It requires a 5 V/100 mA power supply for normal operation. The 5 V power supply should be connected to the clip leads VPOS and COMMON. RF INPUT and LO INPUT ports take RF and LO input signals via edge-mounted SMA connectors. The IF port, labeled IF_OUT+, is configured for single-ended signaling via a balun transformer.
