Description

The TriQuint TGA4705-FC is a flip-chip low noise amplifier (LNA) 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 tp 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.

The part is lead-free and RoHS compliant.
