The HFA3102 is an all NPN transistor array configured as dual differential amplifiers with tail transistors. Based on Intersil bonded wafer UHF-1 SOI process, this array achieves very high fT (10GHz) while maintaining excellent hFE and VBE matching characteristics over temperature. Collector leakage currents are maintained to under 0. 01nA.
