It is mentioned in the manual of HMC8038 that it should be operated at a frequency greater than 100MHz. I have a series of applications. The operating frequency may be 40MHz, 80MHz or 160MHz. We plan to use HMC8038, but I am worried about its performance at 40MHz and 80MHz. Do I need to turn to other products (such as HMC849A) in these two applications? If it is not so necessary, I don't want to use two kinds of SW in our applications.
