General Description
The TriQuint 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
TriQuint’s pHEMT process; the VCO and the
prescaler are manufactured using TriQuint’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.
