Product Number: HMC8205BF10
Hello Everyone.
HMC8205BF10 Gan amplifier requires a gate bias voltage with a voltage value that translates the drain current consumption to 1.4A.
Obviously this will not stay stable at higher temperatures, so now that I am designing the bias controller circuit and i would like to add a temperature compensation sub-circuit.
The problem is that cant find on the datasheet any reference or chart that indicates how many mV per degree celcius are needed to maintain a constant drain current.
I found from other amplifiers that this is usually 0.4mV per degree celcius.
Does that value applies to this particular amplifier? is there any internal note about that parameter?
