HMC903, HMC347A, HMC1082 and HMC797: About phase variation in same wafer lot

Thread Summary

The user inquired about the phase variation of HMC903LP3E, HMC347ALP3E, HMC1082LP4E, and HMC797AMP5E on the same wafer lot, aiming for a phase variation of ±7 degrees before input to the combiner. The engineer responded that typical part-to-part variance is around 17 degrees, which is common for GaAs devices, and that Analog Devices does not support production screening for phase. Calibration is recommended to address phase variations in phased array systems.

Hi,

Please see the attached block diagram.

The customer wants to know the phase variation on the same wafer lot about HMC903LP3E, HMC347ALP3E, HMC1082LP4E and HMC797AMP5E.

Because he uses above products in below blocks and their phase variations should be each other A to D line within ±7 degree before input the conbiner.

Coudl you tell me the phase variation on the same wafer lot about HMC903LP3E, HMC347ALP3E, HMC1082LP4E and HMC797AMP5E?

And can he order those parts with selected phase variation?

Best Regards,

Tomohiro
