I'm calibrating a 8563EC that when it switches bands for frequency response it drops the signal completely and it will not show up again in full until about 200 - 500 MHz after the switch. I checked the biasing on the SLODA and found that the gate bias stays constant, but the SENSE voltages got to ~0. I can't find the issue exactly and am wondering if anyone has insight as to what the problem could be. Thanks!
