DC1233A-A

DC1233A-A is a demo board for the LT5579 1.5GHz to 3.8GHz high linearity upconverting mixer. The LT5579 is a high performance upconverting mixer IC optimized for output frequencies in the 1.5GHz to 3.8GHz range. It features single-ended LO input and RF output ports to simplify board layout and to reduce system cost. The LT5579 offers a superior alternative to passive mixers. Unlike passive mixers which have conversion loss and require high LO drive levels, the LT5579 delivers conversion gain at significantly lower LO input levels and is less sensitive to LO power level variations. Only -1dBm of LO power is needed, and the balanced design results in low LO signal leakage to the RF output. The lower LO drive level requirements, combined with the excellent LO leakage performance, translate into lower LO signal contamination of the output signal.
