The LT5512 is an active double-balanced mixer IC, optimized for high linearity HF, VHF and UHF applications. The IC includes an integrated LO buffer amplifi er to drive the mixer and an RF buffer amplifi er for improved LO-RF isolation. Internal bias circuits eliminate the need for precision external resistors and allow the device to be powered-down using the enable control (EN) pin.
The externally matched RF and IF ports allow the mixer to be used at very low frequencies, below 1MHz or up to 3GHz. The differential LO input is designed for single-ended or a differential input drive.
The LT5512 is a high-linearity alternative to passive diode mixers. Unlike passive mixers, which have conversion loss and require high LO drive levels, the LT5512 delivers conversion gain and requires signifi cantly lower LO drive levels.
