The LTC5556 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.

Enable pins for each channel allow fast turn-on and shutdown. A reduced power mode is also available.

The device has the same functionality as the LTC5566, but the mixers are optimized for a higher 3GHz to 7GHz RF frequency range and the IF is optimized for use up to 900MHz. The mixers may be used down to 1.5GHz, or up to 8GHz with degraded performance.

Product Details

Demonstration circuit 2693A is optimized for evaluation of the LTC®5556 dual programmable gain downconverting mixer. Each channel incorporates an active mixer and a digital IF VGA with 15.5dB gain control range. The IF gain of each channel is independently programmable through the SPI in 0.5dB steps. Its single-ended RF ports have a range from 1.5GHz to 7GHz. The LO port is internally matched to 50Ω from 500MHz to 8GHz with 9dB return loss. The differential IF port is usable from 1MHz to 1000MHz. There is a reduced power mode available through the SPI or RP pin, which lowers the total current consumption by 25%.
