The HFA3046, HFA3096, HFA3127 and the HFA3128 are ultra high frequency transistor arrays that are fabricated from the Renesas complementary bipolar UHF-1 process. Each array consists of five dielectrically isolated transistors on a common monolithic substrate. The NPN transistors exhibit a fTof 8GHz while the PNP transistors provide a fTof 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. Application note AN9315 illustrates the use of these devices as RF amplifiers.

The HFA3101 is an all NPN transistor array configured as a Multiplier Cell. Based on Intersil's bonded wafer UHF-1 SOI process, this array achieves very high fT (10GHz) while maintaining excellent hFEand VBEmatching characteristics that have been maximized through careful attention to circuit design and layout, making this product ideal for communication circuits. For use in mixer applications, the cell provides high gain and good cancellation of 2nd order distortion terms.

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.
