PERFORMANCE
DESCRIPTION
NEC's UPA811T 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
fT, low voltage bias and small size make this device ideally
suited for pager and other hand-held wireless applications.

Notes:
1.Pulsed measurement, pulse width ≤ 350 µs, duty cycle ≤ 2 %.
2.The emitter terminal should be connected to the ground terminal of the 3 terminal capacitance bridge.
For Tape and Reel version use part number UPA811T-T1, 3K per reel.
