Band Switching Diodes - Dual, Series in SOT-323
Description
The main purpose of the BA892V-04W is the Band
Switching. Biased with a DC forward current for sig-
nals 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 resis-
tance 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.
Features
• Low forward resistance
• Small reverse capacitance
e3
• Lead (Pb)-free component
• Component in accordance to
RoHS 2002/95/EC and WEEE 2002/96/EC
