I present small angular scale CMB temperature anisotropy measurements from observations with the QUaD telescope at 100 and 150 GHZ. The resulting TT power spectra indicate significant bandpower detections up to multipoles of ell 2800. Removing discrete foreground sources from our maps and estimating the their residual effect on the spectra is critical to the analysis. Precise measurement of the telescope beam to mitigate systematic effects is also crucial. This work follows up on results by CBI and ACBAR that claim a significant detection of excess power over the LCDM+SZ expectation at these scales.
