Desription
The TriQuint TGS2306-EPU is a GaAs
single-pole, double-throw (SPDT) FET
monolithic switch designed to operate
over the DC to 18GHz frequency range.
This switch not only maintains a high
isolation loss and a low insertion loss
across a wide bandwidth, but also has
very low power consumption and high
power handling of 29dBm or greater
input P1dB at VC = 5V. These
advantages, along with the small size of
the chip, make the TGS2306-EPU ideal
for use in high-speed radar and
communication applications.

Chip Assembly & Bonding Diagram
GaAs MMIC devices are susceptible to damage from Electrostatic Discharge. Proper precautions should
be observed during handling, assembly and test.
TGS2306-EPU
For optimum insertion loss and return loss, a single 0.001” bondwire of length
35 mils should be used. This will be approximately 0.42nH. Differences in
bondwire length will have an impact on switch performance.
VC1 & VC2 can be applied from either side of the MMIC.
DC blocks are required for the RF input and output.

GaAs MMIC devices are susceptible to damage from Electrostatic Discharge. Proper precautions should
be observed during handling, assembly and test.
Reflow process assembly notes:
• Use AuSn (80/20) solder with limited exposure to temperatures at or above 300°C.
(30 seconds maximum)
• 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.
• Maximum stage temperature is 200°C.
