Agilent ATF-501P8 High Linearity
Enhancement Mode[1]
Pseudomorphic HEMT in
2x2 mm2 LPCC[3] Package
Data Sheet
Description
Agilent Technologies’s ATF-
501P8 is a single-voltage high
linearity, low noise E-pHEMT
housed in an 8-lead JEDEC-
standard leadless plastic chip
carrier (LPCC[3]) package. The
device is ideal as a medium-
power amplifier. Its operating
frequency range is from 50 MHz
to 6 GHz.
The thermally efficient package
measures only 2mm x 2mm x
0.75mm. Its backside
metalization provides excellent
thermal dissipation as well as
visual evidence of solder reflow.
The device has a Point MTTF of
over 300 years at a mounting
temperature of +85ºC. All devices
are 100% RF & DC tested.

Pin Connections and
Package Marking
Note:
Package marking provides orientation and
identification:
“0P” = Device Code
“x” = Date code indicates the month of
manufacture.
Notes:
1. Enhancement mode technology employs a
single positive Vgs, eliminating the need of
negative gate voltage associated with
conventional depletion mode devices.
2. Refer to reliability datasheet for detailed
MTTF data.
3. Conforms to JEDEC reference outline MO229
for DRP-N.
4. Linearity Figure of Merit (LFOM) is essentially
OIP3 divided by DC bias power.

Notes:
5. Distribution data sample size is 300 samples taken from 3 different wafers and 3 different lots.
Future wafers allocated to this product may have nominal values anywhere between the upper and
lower limits.
6. Measurements are made on production test board, which represents a trade-off between optimal
OIP3, P1dB and VSWR. Circuit losses have been de-embedded from actual measurements.

1. S parameter is measured on a microstrip line
made on 0.025 inch thick alumina carrier. The
input reference plane is at the end of the gate
lead. The output reference plane is at the end
of the drain lead.
