    Qorvo's TGC4408-SM is a low cost Ku band downconverter. It provides in a single package a dual band VCO, a subharmonic mixer and all the associated gain stages required to integrate the VCO and the mixer. The TGC4408-SM provides a differential signal at 1/4th the VCO frequency for use in a phase-locked loop.

    The subharmonic mixer is manufactured using Qorvo's pHEMT process; the VCO and the prescaler are manufactured using Qorvo's HBT process. The TGC4408-SM is available as a single surface mount 32 lead 5x6 QFN package and is ideally suited for VSAT ground terminals and millimeter wave communication receivers.

    Lead-free and RoHS compliant. Evaluation Boards are available upon request.
