... 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 deliv- ers conversion gain and requires signifi cantly lower LO drive levels. , LTC and LT are registered trademarks of Linear Technology Corporation. ...

... LT5512 U U APPLICATIO S I FOR ATIO The LT5512 consists of a double-balanced mixer, RF buffer amplifi er, high-speed limiting LO buffer and bias/enable circuits. The differential RF, LO and IF ports require simple external matching which allows the mixer to be used at very low frequencies, below 1MHz 3GHz. Low side or high side LO injection can be used ...
