Product Description
The TriQuint TGA4705-FC is a flip-chip low noise
amplifier designed to operate at frequencies that
target the automotive RADAR market. The
TGA4705-FC is designed using TriQuint’s proven
0.13 µm pHEMT process and front-side Cu / Sn
pillar technology for reduced source inductance
and superior noise performance at frequencies of
72 – 80 GHz. Die reliability is enhanced by using
TriQuint’s BCB polymeric passivation process.
The TGA4705-FC is a low noise amplifier that
typically provides 23 dB small signal gain with 5 dB
noise figure at 77 GHz. The TGA4705-FC is an
excellent choice for applications requiring low
noise in receive chain architectures.
Lead-free and RoHS compliant.
