16-Lead (4mm Г— 4mm) QFN Package The LTВ®5527 active mixer is optimized for high linearity,
wide dynamic range downconverter applications. The
IC includes a high speed differential LO buffer amplifier
driving a double-balanced mixer. Broadband, integrated
transformers on the RF and LO inputs provide single-ended
50О© interfaces. The differential IF output allows convenient …
