DC2460A - LTC5566 | 300MHz - 6GHz Dual Programmable Gain Downconverting Mixer (Featuring LTC5566) (Companion Board DC2026C; Linduino Software Optional)
Demonstration circuit 2460A is optimized for evaluation of the LTC®5566 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 are tunable via the SPI or parallel control lines and have a range from 300MHz to 6GHz. The LO port is always matched to 50Ω 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%.

Linduino
Linduino is an Arduino compatible platform for developing and distributing firmware libraries and code for SPI and I²C-compatible integrated circuits. The Linduino One board interfaces to more than 300 QuikEval demonstration cards, supporting a variety of product types including analog-to-digital converters (ADCs), digital-to-analog converters (DACs), power monitors, and more. Firmware libraries for individual devices are written in C and designed to be portable to a wide variety of processors and microcontrollers. Each library has a demonstration program that can be uploaded to the Linduino One platform to allow the circuit and software to be quickly and easily verified.
