Hi all !
I am wondering if any of you have been using PIN diode circuits as variable attenuators...
The actual question is whether or not the diode's behavior as a variable resistance (which is exploited in the variable attenuator) is very sensitive to temperature variations...
In the HSMP-381x diode (Agilent) there's the following attached plot in which for a constant bias current the variation with temperature is small...
Any technical experience on this matter would be helpful !
TIA
