Overview

Description

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 fT of 8. 5GHz, while the PNP transistors have an fT 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 fT enables the design of UHF amplifiers which exhibit exceptional stability.
