RF wideband transistor selection guide on www.nxp.com/rftransistors
Easy-to-use parametric filters help you choose the right RF wideband
transistor for your design.
Why choose NXP’s wideband transistors:
st
th
`
Broad portfolio (1 - 7 generation)
`
Short lead time

Volume delivery
Wideband transistors
The f
T
-I
C
curve represents transition frequency (f
T
)
characteristics as a function of collector current (I
C
) for the seven
generations of RF wideband transistors. A group of transistors
having the same I
C
and similar f
T
represents a curve. The curve
number matches with products in the selection tables of
this section (third column of each table), detailing their RF
characteristics.
