DC733A

DC733A is a LT5519EUF high linearity upconverting mixer demonstration board. The LT®5519 is a 0.7GHz to 1.4GHz high linearity upconverting mixer optimized for wireless and cable infrastructure applications. A high-speed, internally matched LO amplifier drives a double-balanced mixer core allowing the use of a low power, single-ended LO source. An RF output transformer is integrated, thus eliminating the need for external matching components at the RF output, while reducing system cost, component count, board area and system-level variations. The IF port can be easily matched to a broad range of frequencies for use in many different applications. Demonstration circuit 733A is designed for an RF output frequency range from 0.7GHz to 1.4GHz and is optimized for a 140MHz IF input frequency.
