Are there any problems using this part with a low-side LO for sub-GHz RF? The specs look fine but the examples (figure 1) are all high side injection for RF below 1GHz. Any reason?
In our specific case, it's LO=854MHz RF=899MHz IF=45MHz, part=LTC5577IUF#PBF.
There's no reason that the LTC5577 can't be used with low side LO injection for your application. Just be sure to match the ports to the frequency range of interest, and the mixer should work as expected.
