I had used HMC423 mixer in one of the module which was used in upconverting 308MHz IF with 960MHz as LO to generate 1268 MHz RF. As the HMC423 became obsolete, I found suggested alternate part HMC608 in analog site.
But I got doubt as RF frequency range is shown split which does not cover 1.1 to 1.4 GHz. I just wanted to know whether it can be used for my application.
This is the screen shot of HMC686 specification.
