RF Bipolar transistors

3.3.1 Wideband transistors

Why choose NXP’s wideband transistors:

` Broad portfolio (1

st - 7th generation)

` Short lead time

` Smallest packages

` Volume delivery

Wideband transistors line-up per frequency

Wideband transistors

The fT-IC curve represents transition frequency (fT)

characteristics as a function of collector current (IC) for the seven

generations of RF wideband transistors. A group of transistors

having the same IC and similar fT 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.

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.
