RF Power Supplies: Wide-bandgap materials drive a leap in performance, fueled by dual growth engines—communications and semiconductor demand.
In 2025, the RF power supply industry is experiencing a dual surge—driven by both technological iteration and market expansion—while the large-scale application of wide-bandgap semiconductor materials has emerged as a key breakthrough. Data shows that silicon carbide and gallium nitride devices have boosted the power density of power modules to over 15 watts per cubic inch. The market size for wide-bandgap semiconductor materials is expanding at a compound annual growth rate of 45%. In the communications sector, the high-precision demands spurred by 6G R&D are driving RF power supplies to break through to GHz-level operating frequencies. Meanwhile, the semiconductor manufacturing industry’s pursuit of advanced processes below 14nm further necessitates power supplies with an output accuracy of ±0.1% and millisecond-level dynamic regulation capabilities.
At the supply chain level, fluctuations in raw material prices are locked in a strategic interplay with efforts to substitute domestic products. In 2023, copper price volatility caused the average gross profit margin of power supply companies to decline by 1.8 percentage points. Meanwhile, the self-sufficiency rate of domestically produced power supply chips has risen to 42%, and the ongoing localization of key materials has driven industry-wide cost reductions of 8% to 12%. On the policy front, the "Blue Book on the Development of New Power Systems" clearly sets a target of achieving a domestic production rate of over 95% for critical equipment and materials by 2030. Coupled with special funding from the Manufacturing Transformation and Upgrading Fund, this is accelerating the shift of RF power supplies from “import dependence” toward “self-reliance and controllability.” It is projected that by 2025, the global RF power supply market will surpass 30 billion yuan, with the communications and semiconductor sectors accounting for over 60% of the incremental demand.
