COMARK Communications introduced the MPTV‐8000 Medium Power TV series of solid-state DTV transmitters at the 2013 NAB Show.

The MPTV‐8000 series is available in both air- and liquid-cooled, and the product family covers 2kW through over 20kW output power levels. The MPTV‐8000 solid-state transmitters use Doherty amplifier technology along with the latest 50VDC LDMOS devices.

The MPTV‐8000 solid state transmitters use DOHERTY amplifier technology along with the latest 50VDC LDMOS devices.

Doherty solid-state amplifiers bias the transistors in both Class AB and Class C to improve linearity and efficiency, which approaches 40 percent. Another inherent benefit of Doherty-based solid-state amplifiers is they operate cooler than a comparable Class AB, which helps improve system reliability.

The MPTV‐8000 is equipped standard with the COMARK ATSC‐8000DTV exciter in either single-drive or dual-drive configuration.
