General Description
TriQuint’s 0.5 µm pHEMT process is based on our production
released 0.25 µm gate process. TQPHT substitutes lower cost
optical lithography in place of e-beam and adds TriQuint’s
unique thick metal scheme. This process is targeted for high
efficiency and linearity in power amplifiers, low noise amplifiers,
and linear, low loss and high isolation RF switch applications.
The TQPHT process offers a D-Mode pHEMT with a –0.8 V
pinch off. The three metal interconnecting layers are encapsu-
lated in a high performance dielectric that allows wiring flexibil-
ity, optimized die size and plastic packaging simplicity. Precision
NiCr resistors and high value MIM capacitors are included al-
lowing higher levels of integration, while maintaining smaller,
cost –effective die sizes.
Applications
• Highly Efficient and Linear
Power Amplifiers
• Low Loss, High Isolation
Switches for Wireless Trans-
ceivers and Basestations
• Higher Supply Voltage Applica-
tions
• Integrated RF Front Ends–
