this is the block diagram of HMC1122, when I was testing this IC using multimeter
I found that:
1. pin 5 and pin 6 are connected with package base GND.
2. pin 7,8 to pin 12 are connected together with pin 6 and pin 13 in DC.
3. pin 7,8 to pin 12 are NOT connected with package base in DC.
Is that normal or I have bought some fake IC?
Look forward for your reply,thank you.
sorry to border you, I met this problem because I got a fake IC.
