• For mixers, like the HMC526, can LO leakage be improved by adjusting independent DC offsets into the IQ pins?

    I'm interested in software control of the IQ inputs to mixers such as the HMC526, HMC520 and HMC1056.

    Are the IQ inputs of these devices internally biased? Can DC bias voltage on the IQ pins be injected on these pins and adjusted (independently…
