Ultra High Frequency Matched Pair
Transistors
The HFA3134 and HFA3135 are Ultra High Frequency
Transistor pairs that are fabricated with Intersil Corporation’s
complementary bipolar UHF-1X process. The NPN
transistors exhibit an f
T
of 8.5GHz, while the PNP transistors
have an f
T
of 7GHz. Both types exhibit low noise, making
them ideal for high frequency amplifier and mixer
applications.
Both arrays are matched high frequency transistor pairs. The
matching simplifies DC bias problems and it minimizes
imbalances in differential amplifier configurations. Their high
f
T
enables the design of UHF amplifiers which exhibit
exceptional stability.
