Product Description
The TriQuint TGA4706-FC is a flip-chip medium power amplifier designed to operate at the automotive radar frequencies band. The TGA4706FC is designed using TriQuint’s proven 0.13 µm pHEMT process and front-side Cu / Sn pillar technology for simplified assembly and low interconnect inductance. Die reliability is enhanced by using TriQuint’s BCB polymeric passivation process. The TGA4706-FC typically provides 14 dBm saturated output power with 15 dB small signal gain at 77 GHz. Lead-free and RoHS compliant.

These ratings represent the maximum operable values for this device. Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device and / or affect device lifetime. These are stress ratings only, and functional operation of the device at these conditions is not implied. Combinations of supply voltage, supply current, input power, and output power shall not exceed the maximum power dissipation listed in Table IV.
