The HMC451LC3 amplifier supply

abcdhm8@163.com on Jul 6, 2017

Hi：

Can the HMC451LC3 amplifier supply pins (13 pins and 16 pins) be connected together?

If the power supply can not be connected together, please give the best power supply connection scheme.

Thanks!

Hello abcdhm8@163.com,

The following EZ thread describes the best drain bias connections and bypassing for the HMC451LP3...which contains the same die as the HMC451LC3 though the two parts have their Vdd pins offset from each other by one pin.

The gerber file link from the thread above is for the LP3 part...so below I've provided a link to the gerber files for the LC3 part:

Let me know if you have additional questions.

Regards,

SMcBride
