HMC8205BF10 pin voltage issue

Thread Summary

The user encountered a stable 10 ohm impedance on VDD1 when applying -5V to VGG, making the device unusable. The final answer suggests biasing the device with VDD at the nominal voltage level. Another user reported a similar issue with -8V at VGG1 and asked if the suggested solution worked.

When we got it, we didn’t apply any voltage on the VDD pins, but when we applied the Vgg in blocking level (-5V), measuring the impedance on the Vdd1 it was stable at 10 ohms, regardless of the Vgg level. we cannot use it.

It's not clear to me how to fix this.
