Product Description
The TriQuint TGF2022-48 is a discrete 4.8 mm pHEMT which operates from DC-20 GHz. The TGF2022-48 is designed using TriQuint's proven standard 0.35um power pHEMT production process. The TGF2022-48 typically provides > 37 dBm of saturated output power with power gain of 13 dB. The maximum power added efficiency is 58% which makes the TGF2022-48 appropriate for high efficiency applications. The TGF2022-48 is also ideally suited for Point-to-point Radio, High-reliability space, and Military applications. The TGF2022-48 has a protective surface passivation layer providing environmental robustness.

These ratings represent the maximum operable values for this device. Combinations of supply voltage, supply current, input power, and output power shall not exceed PD. For a median life time of 1E+6 hrs, Power dissipation is limited to: PD(max) = (150 C - TBASE C) / 17.3 (C/W) Junction operating temperature will directly affect the device median time to failure (TM). For maximum life, it is recommended that junction temperatures be maintained at the lowest possible levels.

Assembly Process Notes
Reflow process assembly notes: * * * * * Use AuSn (80/20) solder with limited exposure to temperatures at or above 300 C for 30 sec An alloy station or conveyor furnace with reducing atmosphere should be used. No fluxes should be utilized. Coefficient of thermal expansion matching is critical for long-term reliability. Devices must be stored in a dry nitrogen atmosphere.
Component placement and adhesive attachment assembly notes: * * * * * * * Vacuum pencils and/or vacuum collets are the preferred method of pick up. Air bridges must be avoided during placement. The force impact is critical during auto placement. Organic attachment can be used in low-power applications. Curing should be done in a convection oven; proper exhaust is a safety concern. Microwave or radiant curing should not be used because of differential heating. Coefficient of thermal expansion matching is critical.
Interconnect process assembly notes: * * * * * Thermosonic ball bonding is the preferred interconnect technique. Force, time, and ultrasonics are critical parameters. Aluminum wire should not be used. Devices with small pad sizes should be bonded with 0.0007-inch wire. Maximum stage temperature is 200 C.
