Not such a big deal anymore. Synthesizers were once racks of equipment, then boards, then hybrid modules, then chips, and now they are just part of a chip! I can remember about 10 years ago being amazed at Silicon Labs' synthesizers with the VCO on-chip. We were all over those at Powerwave for the smaller size, lower cost, greater availability, and higher reliability versus the modules we had been buying from M/A-COM and others. About the only thing that was inferior was the variation in output power, but we found ways around that because the advantages were so compelling. Now at Broadcom, we have multiple synthesizers on a chip. Moore's law in action, although analog circuits like this don't scale nearly as well as digital.
