Data Sheet
Description
Agilent Technologies’s ATF-521P8 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, high-linearity am-
plifier. Its operating frequency range
is from 50 MHz to 6 GHz.
The thermally efficient package mea-
sures only 2mm x 2mm x 0.75mm. Its
backside metalization provides excel-
lent thermal dissipation as well as vi-
sual evidence of solder reflow. The
device has a Point MTTF of over 300
years at a mounting temperature of
+85°C. All devices are 100% RF & DC
tested.

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