AD8343 is a high-performance broadband active mixer with wide bandwidth on all ports and very low intermodulation distortion, well suited for demanding transmit applications or complex receiver applications.
The AD8343 is a high‑performance broadband active mixer covering DC to 2.5 GHz. It offers a typical conversion gain of 7 dB, low LO drive (‑10 dBm), and a differential 50 Ω input impedance, allowing direct connection to differential filters or balun‑based single‑ended sources. The device operates from a single 5 V supply with typical quiescent current of 50 mA and includes a power‑down mode drawing only 20 µA.
Typical applications include cellular base stations, wireless LAN, satellite converters, SONET/SDH radio links, and RF instrumentation. The mixer provides separate differential LO, IF, and RF ports, and its pinout and interface schematics are detailed for easy integration on evaluation boards.
