T1P3005028-SP
50 W, 28V, 500 MHz—2GHz, Pulsed, Powerband
TM
pHEMT RF Power Transistor
Introduction
The T1P3005028-SP is a POWERBAND
TM
discrete pHEMT,
depletion mode, RF Power transistor designed to operate from
500MHz to 2GHz in wide-band circuits. The device has an in-
stantaneous band-width P1dB output power of 50watts across
the entire band when operated in the TriQuint wide-band test
fi
xture. The T1P3005028-SP can also be used in narrow band ap-
plications and is rated at 65Watts P1dB at 2GHz.

1/ These ratings represent the maximum operable values for this
device.
2/ Combinations of supply voltage, supply current, input power,
and output power shall not exceed PD.
3/ For a median life
ti
me of 1E+6 hrs, Power dissipation is limited
to: PD(max) = (150 °C – TBASE °C) / 3.5 (°C/W)
4/ Junction operating temperature will directly affect the device
median
ti
me to failure(TM). For maximum life, it is recom-
mended that junction temperatures be maintained at the lowest
possible levels.
