ATF-521P8
High Linearity Enhancement Mode[1] Pseudomorphic HEMT
in 2x2 mm2 LPCC[3] Package
Data Sheet
Description
Avago Technologies’ ATF521P8 is a singlevoltage high
linearity, low noise EpHEMT housed in an 8lead JEDEC
standard leadless plastic chip carrier (LPCC[3]) package.
The device is ideal as a mediumpower, highlinearity
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 +85°C. All
devices are 100% RF & DC tested.

“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 DRPN
4. Linearity Figure of Merit (LFOM) is essentially OIP3 divided by DC
bias power.
