FEATURES
DESCRIPTIOU
The LT
5512 is a broadband mixer IC optimized for high
linearity downconverter applications including cable and
wireless infrastructure. The IC includes a differential LO
buffer amplifier driving a double-balanced mixer. An inte-
grated RF buffer amplifier improves LO-RF isolation and
eliminates the need for precision external bias resistors.
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 significantly lower LO drive
levels.
