General Description
The TriQuint TGC4546-SM is a Ka-Band Upconverter with integrated LO buffer amplifier and quadrupler, housed in a 28 lead 5x5 mm QFN package. The TGC4546-SM operates from an RF of 36 to 45 GHz and LO from 8.1 to 10.4 GHz with IF inputs from DC to 3.5 GHz and is designed using TriQuint’s pHEMT production process.
The TGC4546-SM typically provides 27 dBm of output TOI, and 11 dB of conversion gain.
Lead-free and RoHS compliant.
