Comark Announces the EC700MP Transmitter

Company will introduce new series of medium-power, air-cooled transmitters at the 2019 NAB Show.

Hitachi Kokusai Electric Comark has announced the introduction of new series high-efficiency, air-cooled solid state UHF DTV transmitters. The new the E-Compact EC700MP series of transmitters support 170W, 350W, and 1kW RF output power levels.

The E-Compact HP series was introduced at the 2016 NAB Show and subsequently “repack-optimized” for the US market with output power levels of up to 10kW. Many HP series transmitters are already on the air, serving stations and viewers throughout the US and Puerto Rico.

The introduction of the E-Compact MP series at the 2019 NAB Show fills out the air-cooled UHF product portfolio with high-efficiency, low power models. All MP and HP series E-Compact transmitters incorporate the latest asymmetric broadband Doherty LDMOS amplifiers, the same device as in PARALLAX series liquid-cooled UHF transmitters. The PA design includes automatic cooling fan speed control that provides lower acoustic noise levels during operation. The E-Compact family also features EXACT-V2 IP Optimized DTV exciters with DualCast technology and is easily upgraded from ATSC 1.0 to 3.0, protecting your investment today for use tomorrow.

The EC710MP-BB transmitter is being introduced for customers requiring a compact, 1kW solution. This 1kW transmitter features separate PA and PSU chassis that require only 4RU of space. Future compatibility with both ATSC 1.0 / ATSC 3.0 is ensured, providing the same output power for either standard. The EC710MP-BB features N+1 hot-swap PSU modules, providing 25% PSU redundancy.

The E-Compact family is compact and rugged, perfectly suited for broadcasters looking to upgrade or replace older, less efficient equipment currently in operation, or for future ATSC 3.0 SFN systems. The E-Compact EC710MP-BB 1kW transmitter will be on display at the 2019 NAB Show.
