ATF-531P8
High Linearity Enhancement Mode[1] Pseudomorphic HEMT
in 2x2 mm2 LPCC[3] Package
Data Sheet
Description
Avago Technologies’ ATF‑531P8 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 high linearity, low‑noise, medium‑
power amplier. Its operating frequency range is from 50
MHz to 6 GHz.
The thermally ecient package measures only 2 mm
x 2 mm x 0.75 mm. Its backside metalization provides
excellent thermal dissipation as well as visual evidence
of solder reow. The device has a Point MTTF of over 300
years at a mounting temperature of +85°C. All devices are
100% RF & DC tested.

“3P” = 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.

Gamma Load and Source at Optimum OIP3 Tuning Conditions
The device’s optimum OIP3 measurements were determined using a Maury load pull system at 4V, 135 mA quiesent
bias. The gamma load and source over frequency are shown in the table below:

Notes:
1. Fmin values at 2 GHz and higher are based on measurements while the Fmins below 2 GHz have been extrapolated. The Fmin values are based on
a set of 16 noise gure measurements made at 16 dierent impedances using an ATN NP5 test system. From these measurements a true Fmin is
calculated.
2. S and noise parameters are 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.

1. Fmin values at 2 GHz and higher are based on measurements while the Fmins below 2 GHz have been extrapolated. The Fmin values are based on
a set of 16 noise gure measurements made at 16 dierent impedances using an ATN NP5 test system. From these measurements a true Fmin is

Notes:
1. Fmin values at 2 GHz and higher are based on measurements while the Fmins below 2 GHz have been extrapolated. The Fmin values are based on
a set of 16 noise gure measurements made at 16 dierent impedances using an ATN NP5 test system. From these measurements a true Fmin is
calculated.
2. S and noise parameters are 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.
