Cost–Performance Optimization of RF Transmitter Systems: A Quantitative Techno-Economic Framework for Reducing Operational Costs, Improving Energy Efficiency, and Supporting Sustainable Broadcasting Policy Decisions

This study presents a comprehensive quantitative framework for optimizing the cost-performance of radio frequency (RF) transmitter systems, integrating technical, economic, and sustainability perspectives to support informed broadcasting policy decisions. Modern broadcasting networks face increasing pressures to reduce operational costs, enhance energy efficiency, and comply with evolving regulatory standards, necessitating a systematic approach to transmitter system design and deployment. The proposed framework evaluates key performance metrics, including power efficiency, signal fidelity, reliability, and maintenance overhead, alongside economic indicators such as capital expenditure (CAPEX), operational expenditure (OPEX), and lifecycle cost analysis. By applying multi-criteria decision-making (MCDM) techniques and techno-economic modeling, the framework enables identification of optimal trade-offs between performance and cost, facilitating evidence-based selection of transmitter architectures, amplification technologies, and energy management strategies. Case studies involving high-power FM and digital television transmitter networks demonstrate the effectiveness of the approach in reducing energy consumption by up to 18%, decreasing operational costs by 12–15%, and improving overall system reliability without compromising broadcast quality. Sensitivity analyses further reveal the influence of electricity pricing, component efficiency, and maintenance scheduling on the total cost of ownership, providing actionable insights for network operators and policymakers. Importantly, the framework also incorporates sustainability criteria, assessing carbon footprint reduction and alignment with green broadcasting initiatives, thus bridging the gap between technical optimization and environmental responsibility. The findings underscore the critical role of integrated techno-economic assessment in guiding strategic investment, operational planning, and regulatory compliance in modern broadcasting systems. By delivering a scalable and adaptable methodology, this study offers broadcasters and regulators a practical tool for achieving cost-effective, energy-efficient, and sustainable RF transmission, ultimately supporting resilient and environmentally conscious media infrastructure.
