Product Details

The LTC5566 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.

Programmable RF input tuning via the SPI or parallel control lines makes the device attractive for wideband radio applications. Furthermore, a reduced power mode is available, programmed through the SPI.

Integrated RF transformers provide single-ended 50Ω 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 mixers are optimized for use up to 5GHz but may be used up to 6GHz with degraded performance.
