We will use an HMC6981LS6 amplifier and we will use an active bias controller to guarantee its correct behavior.
After taking a look at the selection product table for these controllers:
and looking at each of the parts datasheets, I am pretty sure that the HMC981LP3E can meet the HMC6981LS6 specifications.
If I am not wrong the HMC980LP4E also could meet the amplifier specifications (I have to study more in depth its datasheet), but the former is perhaps simpler to configure.
Could you also confirm if I am on the right choice ?
BTW, The HMC981LP3E datasheet states that VGATE High Level maximum value is of VG_MAX = VNEG+4.5 V.
In which case this signal can rise up to VG_MAX ?
I ask this because if I have VNEG set to -3 V, VNEG+4.5 V could damage the HMC6981, since its gate voltage range is specified from -3V to 0 V.
Thanks in advance,
HMC6981 to HMC6981LS6 in title
