DC2460A, Demo Board based on LTC5566 300MHz to 6GHz Dual Programmable Gain Down converting Mixer

Descripción

• DC2460A, Demonstration circuit is optimized for evaluation of the LTC5566 dual programmable gain down converting 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 are tunable via the SPI or parallel control lines and have a range from 300MHz to 6GHz. The LO port is always matched to 50-Ohm from 150MHz to 6GHz with 10dB return loss. The differential IF port is usable from 1MHz to 500MHz. There is a reduced power mode available through the SPI, which lowers the total current consumption by 25%
