DC2091A - LTC5599 | 30MHz to 1300MHz Low Power Direct I/Q Modulator - DC590B Serial Board Required
Demonstration circuit 2091A is optimized for evaluation of the LTC®5599 low power direct quadrature modulator. The balanced I and Q baseband input ports can be either AC- or DC-coupled to a source with a common mode voltage level of about 1.4V. Fixed LC networks on the LO and RF ports cover a continuous 90MHz to 1300MHz range. The SPI interface controls the supply current, modulator gain, and allows optimization of the LO carrier feedthrough and side-band suppression.

Software
QuikEval System
The QuikEval system is a USB-based product demonstration and data acquisition system that allows users to quickly evaluate the performance of Linear Technology products. The system consists of a USB Data Acquisition Controller board (DC590B) that connects to individual daughter cards for specific Linear Technology products.
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.
