Overview
The AD8343ARU-REEL7 is a high-performance broadband active mixer produced by Analog Devices Inc. This component is fabricated on Analog Devices' high-performance 25 GHz silicon bipolar IC process and is available in a 14-lead TSSOP package. The AD8343 is designed for demanding transmit and receive channel applications, offering wide bandwidth on all ports and very low intermodulation distortion.
It operates with a single 5 V supply, consuming a typical current of 50 mA, and features a power-down mode that reduces the current to 20 μA. The mixer provides a typical conversion gain of 7 dB and supports differential LO, IF, and RF ports with 50 Ω LO input impedance.
