InP HBT LDMOS RF MEMS FPD2250 1.5W POWER pHEMT The FPD2250 is an AlGaAs/InGaAs pseudomorphic High Electron Mobility Transis- tor (pHEMT), featuring a 0.25 μmx2250 μm Schottky barrier gate, defined by high- resolution stepper-based photolithography. The recessed gate structure minimizes parasitics to optimize performance. Th e epitaxial structure and processing have been optimized for reliable high-power applications. The FPD2250 is also available in the low-cost plastic SOT89 package. 32dBm Linear Output Power at 12GHz 7.5dB Power Gain at 12GHz 42dBm OIP3 45% Power-Added Efficiency

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=5.0- (0.033W/°C)xT HS, where THS=heatsink or ambient temperature above 22°C. Example: For a 85°C carrier temperature: PTOT=5.0-(0.033x(85-22))=2.9W 4Total Power Dissipation (PTOT) defined as (PDC+PIN)–P OUT, 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.

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 onto the top face of the die. Ideally it should not exceed half the chip height. For automated dispense Ablestick LMISR4 is recommended and for manual dispense Ablestick 84-1 LMI or 84-1 LMIT are recommended. These should be cured at a temperature of 150°C for one 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 at used 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 th ermocompression wedge bonding with 0.001” (25µm) diameter wire. Bond force, time stage temperature and ultrasonics are al l critical parameters and the settings are dependent on the setup being used and application. 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 Electro- static Discharge (ESD) precautions should be ob served at all stages of storage, handling, assembly, and testing. 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. This is an unpackaged part and therefore no MSL rating applies. Application Notes and Design Data Application Notes and design data in cluding S-parameters and device model are available on request and from www.rfmd.com. Reliability An MTTF of 4.2 million hours at a channel temperature of 150°C is achieved for the process used to manufacture this device.
