HFA3101
Gilbert Cell UHF Transistor Array
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 f
T
(10GHz) while
maintaining excellent h
FE
and V
BE
matching 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.

NOTE: Intersil Pb-free products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which is compatible with both SnPb and
Pb-free soldering operations. Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed
the Pb-free requirements of IPC/JEDEC J STD-020C.
