FPD1050

0.75W POWER pHEMT

The FPD1050 is an AlGaAs/InGaAs pseudomorphic High Electron Mobility Transis-

tor (pHEMT), featuring a 0.25μmx1050μm Schottky barrier gate, defined by high-

resolution stepper-based photolithography. The double recessed gate structure

minimizes parasitics to optimize performance. The epitaxial structure and process-

ing have been optimized for reliable high-power applications. The FPD1050 is also

available in the low-cost plastic SOT89 package.

Notes:

1TAMBIENT =22°C unless otherwise noted; exceeding any one of these absolute max-

imum ratings may cause permanent damage to the device.

2Operating at absolute maximum VD continuously is not recommended. If operation

at 10V is considered then IDS must be reduced in order to keep the part within

its thermal power dissipation limits. Therefore VGS is restricted to <-0.5V.

3Total Power Dissipation to be de-rated as follows above 22°C: PTOT =3.4-

(0.022W/°C)xTHS, where THS = heatsink or ambient temperature above 22°C.

Example: For a 85°C carrier temperature: PTOT =3.4-(0.022x(85-22))=2.01W

4Total Power Dissipation (PTOT) defined as (PDC+PIN)–POUT, where PDC: DC Bias

Power, PIN: RF Input Power, POUT: RF Output Power.

5Users should avoid exceeding 80% of 2 or more Limits simultaneously.

6Thermal Resistivity specification assumes a Au/Sn eutectic die attach onto an Au-

plated copper heatsink or rib.

Exceeding any one or a combination of the Absolute Maximum Rating conditions may

cause permanent damage to the device. Extended application of Absolute Maximum

Rating conditions to the device may reduce device reliability. Specified typical perfor-

tions is not implied.

Preferred Assembly Instructions

GaAs devices are fragile and should be handled with great care. Specially designed collets should be used where possible.

The back of the die is metallized and the recommended mounting method is by the use of conductive epoxy. Epoxy should be

applied to the attachment surface uniformly and sparingly to avoid encroachment of epoxy on to the top face of the die and

ideally should not exceed half the chip height. For automated dispense Ablestick LMISR4 is recommended. For manual dis-

pense Ablestick 84-1 LMI or 84-1 LMIT are recommended. These should be cured at a temperature of 150°C for 1 hour in an

oven especially set aside for epoxy curing only. If possible, the curing oven should be flushed with dry nitrogen. The gold-tin

(80% Au 20% Sn) eutectic die attach has a melting point of approximately 280°C but the absolute temperature being used

depends on the leadframe material used and the particular application. The maximum time should be kept to a minimum.

This part has gold (Au) bond pads requiring the use of gold (99.99% pure) bondwire. It is recommended that 25.4mm diameter

gold wire be used. Recommended lead bond technique is thermocompression wedge bonding with 0.001” (25µm) diameter

wire. Bond force, time stage temperature, and ultrasonics are all critical parameters and the settings are dependant on the

setup and application being used. Ultrasonic or thermosonic bonding is not recommended.

Bonds should be made from the die first and then to the mounting substrate or package. The physical length of the bondwires

should be minimized especially when making RF or ground connections.

Handling Precautions

To avoid damage to the devices, care should be exercised during handling. Proper

Electrostatic Discharge (ESD) precautions should be observed at all stages of storage,

handling, assembly, and testing.

ESD/MSL Rating

These devices should be treated as Class 0 (0V to 250V) using the human body model as defined in JEDEC Standard No. 22-

A114. Further information on ESD control measures can be found in MIL-STD-1686 and MIL-HDBK-263.

Application Notes and Design Data

Application Notes and design data including S-parameters and device model are available on request and from

www.rfmd.com.

Reliability

An MTTF of in excess of 4.2 million hours at a channel temperature of 150°C is achieved for the process used to manufacture

this device.
