The LTC5560 from Linear Technologies is a high performance broadband active mixer optimized for both Upconversion and Downconversion applications. It has an RF/LO frequency from 0.01 MHz and 4 GHz. This double-balanced mixer can be driven by a single-ended LO source and requires only –2dBm of LO power. The balanced design results in low LO leakage to the output, while the integrated input amplifi er provides excellent LO to IF isolation. It is available in a small DFN package that measures 3 x 3 mm.
