HMC903

Hello,

 

I have a few questions regarding the HMC903:

 

1. The datasheet of HMC903 specifies bias condition of Vdd1=Vdd2=3.5V

with Idd=90 mA. How does increasing or decreasing Vdd, affect the noise figure

and gain performance of the device? Can you supply us a plot showing noise

figure and gain performance versus Vdd versus frequency?

 

2. The datasheet of HMC903 specifies noise figure of 1.6 dB typical, 2.1

dB max. Does Hittite offer screening of  the devices for lower noise figure

performance? If yes, how do we purchase the devices with lowest noise figure performance?

 

3. Do you have any upcoming 12-18 GHz LNA MMICs with a lower noise figure

than the HMC903? If yes, can you provide information on these MMICs, preliminary datasheets?

 

Thanks,

Best Regards.
