AT-64000
Up to 4 GHz Linear Power Silicon Bipolar Transistor Chip
Data Sheet
Description
The AT-64000 of Avago Technologies is a high perfor-
mance NPN silicon bipolar transistor. This device is
designed for use in medium power, wideband amplifier
and oscillator applications operating over VHF, UHF and
microwave frequencies
Excellent device uniformity, performance and reliability
are produced by the use of ion-implantation, self align-
ment techniques, and golf metallization in the fabrica-
tion of these devices. The use of ion-implanted ballast
resistors ensures uniform current distribution through
the multiple emitter fingers.
