Transmitter Overview

Our family of UHF band solid-state transmitters are built using LDMOS transistor technology. The scalable systems offer up to 12 kW of average power and are designed for digital terrestrial television broadcasting over a UHF frequency range of 474 MHz to 860 MHz.

The modular design includes an ATSC modulator, pre-driver, air-cooled HPA modules, passive combining system and system controller. A power supply sub-system with PDU and hot-swappable AC/DC power supplies is also included. The scalable systems can be customized to operate with 4, 8, 12 or 16 HPA modules, and can be updated in the field as output power requirements change.

The systems also feature a number of monitoring and self-protection circuits including input overdrive, forward power, reflected power and over temperature. The system controller provides a user-friendly interface for monitoring and control of the complete system as well as the individual HPA modules. A front panel display provides the user with local monitoring and control while Ethernet and RS485 interfaces provide the user with local/remote monitoring and control via PC GUI, Web GUI and optional SNMP.

All of the transmitter’s components are enclosed in standard indoor 19” rack mount cabinets.
