Hi, I am looking for an analog phase shifter on 3GHz, and I see ADI has two analog phase shifter IC HMC247 and 877. But the listed lower frequency limit is 5GHz for one and 8GHz for the other. My question is if I could use the devices on 3GHz at all ? I don't care if the phase shift range gets reduced at 3GHz, as long as the rf gets through without too much loss, and the phase control still has some effect. Thanks - H.
