Rohde & Schwarz has added the air-cooled TM1 to its UHF transmitter range, covering output levels from 600 watts to 6.5 kilowatts. The platform supports ATSC 3.0 and 5G Broadcast natively and is positioned for medium-power terrestrial sites.
R&S Auto-Doherty adjusts the amplifier operating point in real time to improve efficiency across changing conditions. The company also says the design follows secure-by-design principles for critical infrastructure. A TM1 renewal option lets operators upgrade existing TMU9 equipment to the new platform's functionality instead of replacing an entire site.
That migration path is the practical significance. Terrestrial networks face pressure to reduce electricity use while adding datacasting, mobile reception and interactive-service options. Reusing cabinets or installed infrastructure can lower disruption and embodied cost, provided the renewal retains the claimed RF and security characteristics.
No comparative efficiency curves, redundancy topology, cooling limits or measured renewal savings are included in the announcement. Network operators will need site-specific performance, regulatory and lifecycle data before choosing an upgrade.
