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.

> 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.

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.

TGF2022-48

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.
