Description
The main purpose of the BA892V-04W is the Band Switching. Biased with a DC forward current for signals at frequencies over 100 MHz up to 3 GHz this
diode behaves like a current controlled resistor and not as a diode any more.
Depending on the forward current the forward resistance rf can be switched far below 1 Ω, so that the Switch is closed.
To open the Switch, the BA892V-04W has to be driven in the reverse mode where the BA892V-04W behaves like a small capacitor with high isolation.
So typical applications for this Band Switching Diode are mobile and TV-applications.
