Mixer-LT5512, LT5526, LT5560, LTC5562


I have RF input signal from 300 kHz to 12 GHz, and IF is 20 MHz. One of the design requirements is active mixer as we want a low LO drive.The frequency conversion will be split into 2 mixers, one covers 300 kHz to about 3 to 4 GHz, and the second one covers from there to 12 GHz. For the first mixer having RF input from 300 kHz to 3/4 GHz, it will need to perform up and downconversion together as the IF is 20 MHz. 


When I looked through the catalogue from ADI, some mixers are labelled as downconverting, while others are "downconverting, upconverting". For example:

LT5512, LT5526 - Downconverting mixer

LT5560, LTC5562 - Downconverting mixer, Upconverting mixer

So, are any of these mixers able to perform both up and downconversion in a single circuit?
