PPT-Linac RF Modulators New Specifications

Trevor Butler Oct 26 th 2011 1030 am 1100 am PIP Linac 200MHz Modulator Working Group New Modulator Specifications WG Started 07202011 Complete 10032011. These direct modulators set the industry standard with outofband noise density as low as 156 dBmHz and carrier and sideband suppression of 35 dBc The RF2483 is an ultralownoise dualband direct modulator with AGC designed for base station application Yue Hao, C-AD.
