Ultra High Frequency Transistor Arrays
The HFA3046, HFA3096, HFA3127 and the HFA3128 are
Ultra High Frequency Transistor Arrays that are fabricated
from Intersil Corporation’s complementary bipolar UHF-1
process. Each array consists of five dielectrically isolated
transistors on a common monolithic substrate. The NPN
transistors exhibit a f
T
of 8GHz while the PNP transistors
provide a f
T
of 5.5GHz. Both types exhibit low noise (3.5dB),
making them ideal for high frequency amplifier and mixer
applications.
The HFA3046 and HFA3127 are all NPN arrays while the
HFA3128 has all PNP transistors. The HFA3096 is an
NPN-PNP combination. Access is provided to each of the
terminals for the individual transistors for maximum
application flexibility. Monolithic construction of these
transistor arrays provides close electrical and thermal
matching of the five transistors.
Intersil provides an Application Note illustrating the use of
these devices as RF amplifiers. For more information, visit
