HMC1133 power supply and Bit 'n'' sequence

EVB: EV1HMC1133LP5 was broken. IL becomes more than 60dB. Vdd (+5V) current becomes too large and IC becomes hot.


Is there specific sequence requirement on power supplies and Bit1 to Bit 6?
Does applying DC to RF1 or RF2 make IC broken?
Does applying RF signal to RF1 or RF2 without power supplies turning on make IC broken?


Best Regards,
