I am currently designing K band VGA with HMC997. Is it possible to use the active bias controller HMC920? I do not see HMC997 in the list of the bias controller possible amplifiers.
Since HMC997 is 5V, 170mA which is in HMC920 range(5-16.5V and up to 500mA), HMC920 can be used.
Please keep in mind in order to change gain , there is one more voltage needed(Vctrl).
