At the 2013 NAB Show, COMARK will showcase the MPTV-8000 medium-power solid-state DTV transmitter, featuring air- or liquid-cooled Doherty amplifiers .
Doherty amplifier technology provides improved linearity as well as higher efficiency.
The MPTV-8000 includes COMARK’s ATSC-8000, a flexible, powerful DTV exciter. The ATSC-8000 features leading RF correction capabilities without the need for an external PC. The exciter is now available with optional local/remote RF performance metrics that include amplitude and group delay as well as SNR and IMD vs. time.
For the LPTV market, COMARK will introduce the VLP-5000 series of transmitters and translators. This series has been developed from the ground up specifically for LPTV operators needing to upgrade, replace or build VHF or UHF stations.
