The DC2091A demonstration board is designed to evaluate the LTC5599 low‑power direct quadrature modulator. It provides balanced I/Q baseband inputs, fixed LC networks covering 90 MHz‑1300 MHz, and an SPI interface for control. The manual includes a description of the circuit, recommended test equipment, and detailed wiring diagrams.
Key sections cover test‑equipment setup, a quick‑start procedure for powering up the board, measurement steps for gain, compression point, image rejection and LO leakage, the full schematic, a complete parts list, and safety/warranty notices. The document also points to design files available on Linear Technology’s website.
