DESCRIPTION
NEC's UPA810T is two NPN high frequency silicon epitaxial
transistors encapsulated in an ultra small 6 pin SMT package.
Each transistor is independently mounted and easily config-
ured for either dual transistor or cascode operation. The high
f
T
, low voltage bias and small size make this device suited for
various hand-held wireless applications.
