I am working with hmc 232A switch. The PCB used is 2 layer Rogers 4350B 10 mil thick. While testing at 9-10 GHz, I am not getting isolation as projected inthe data sheet. Can we cascade three switches to improve isolation to a higher value something like 90 dB. Do I need to house the pcb in an aluminium housing during testing. Can anyone suggest how to proceed to get rated performance.
