Hi,
I am using HMC908A IQ Demodulator evaluation board EV1HMC908ALC5. It worked perfectly fine for two days (as I found phase imbalance at various LO power levels successfully) but on the third day when I connected VDD1 & VDD2 at 3.3V @ 65mA, VDD3 at 5V @ 80mA & GND pins and powered it up VDD3 is drawing more current with no load and showing short circuit. Previously current dissipation was less than 1mA on VDD3 during tests with no load.Please tell me what's just happened?
Regards,
Yumna
