nn 32-Lead (5mm Г— 5mm) QFN Package The LTCВ®5566 dual programmable gain downconverting
mixer is ideal for diversity and MIMO receivers that require
precise gain setting. Each channel incorporates an active
mixer and a digital IF VGA with 15.5dB gain control range.
The IF gain of each channel is programmed in 0.5dB steps
through the SPI. Applications Integrated RF transformers provide single-ended 50О© inputs. The differential LO input is designed for single-ended
or differential drive. The differential IF output simplifies
the interface to differential IF filters and amplifiers. The …
