Maxiva™ UATK-OP / VATK-OP

High-Efficiency UHF & VHF Air-Cooled Digital TV Transmitters

OVERVIEW

GatesAir's Maxiva UATK-OP / VATK-OP Series of high-efficiency air-cooled transmitters deliver power levels from 200W up to 7kW UHF and 12.8kW VHF, with state-of-the-art digital TV transmission capabilities.

The Maxiva UATK-OP / VATK-OP Series transmitter system features several key components:

A software-defined Kintex modulator/exciter (with dual drive option) offering Real-Time Adaptive Correction, multiple input interfaces (ASI & TSoIP), and standard high-stability GPS/GLONASS receiver for precise synchronization
High-efficiency broadband Doherty power amplifiers for all bands (1 to 8 PA modules depending on model and power requirements)
Hot-swappable compact power supplies with 2-of-3 redundancy per PA module
An innovative air-cooling system with variable speed fans for maximum efficiency

Maxiva UATK-OP / VATK-OP Series transmitters support major digital standards including ATSC 1.0, ATSC 3.0 and ISDB-Tb, with a software-upgradeable architecture ensuring future modulation compatibility.

The series incorporates cutting-edge engineering innovations that maximize efficiency, power density and performance while reducing footprint and energy consumption, delivering industry-leading reliability and the lowest total cost of ownership in its class.
