The devices support both immersive audio and warning-sound synthesis for driver-assistance functions. Tier-1 infotainment suppliers disclosed that moving from Class AB to Class D saved 0.5 kWh per 100 km drive cycle, a material figure given range anxiety. As BEV penetration climbs, automotive design wins are expected to elevate Class-D’s revenue share in the power amplifier market at a significant rate by 2030.

LEO Satellite Constellations Driving Ku/Ka-band SSPAs

Regional operators in the Middle East and Africa continued to invest in hundreds of Ku-band gateways paired with solid-state power amplifiers that offer mean-time-between-failures exceeding 100,000 hours. Gilat’s Endurance line replaced traveling-wave tube amplifiers at several teleport sites, reducing maintenance cost and improving linearity for high-order QAM. In parallel, MACOM began sampling a linearized Q-band GaN MMIC that pushes PAE above 25% at 45 GHz, paving the way for higher-throughput laser-com feeder links. With nearly 5,000 LEO craft launched during 2024-2025, Ku/Ka shipments are poised to anchor double-digit revenue growth in the high-frequency tier of the power amplifier market.

GaAs Wafer Supply Constraints Elevating BOM Costs

Gallium availability tightened in late 2024 after export-control measures constrained Chinese refinery output, inflating GaAs epi-wafer pricing by up to 18%. Multilayer RF front-end modules, therefore, faced higher bill-of-materials outlays, pressuring handset OEM margins and encouraging an accelerated pivot toward GaN-on-silicon processes. Finwave Semiconductor signed a foundry pact with GlobalFoundries to commercialize enhancement-mode GaN-on-Si for sub-6 GHz phones, aiming to neutralize GaAs cost volatility. While long-term diversification will damp inflationary risk, short-run sourcing difficulties are trimming the headline CAGR of the power amplifier market by nearly one percentage point.

EU Eco-Design Idle-Power Caps on Audio PAs

Revised Eco-Design directives effective 2024 mandated idle-power draw below 1 W for consumer and commercial audio gear sold in the European Economic Area. Vendors such as Extron updated Class-D network amplifiers with Eco Standby modes that attain 0.5 W quiescent consumption without compromising rapid wake-up. Compliance engineering costs and requalification testing have lengthened product-development cycles, limiting smaller brands’ ability to compete and tempering unit demand in legacy Class AB channels.

Segment Analysis

By Technology: GaN Disrupts GaAs Dominance

GaAs devices retained a 41.0% revenue position in 2024 on the strength of entrenched 1–6 GHz handset sockets, yet GaN shipments surged on macro-cell roll-outs and Ku-band gateways. GaN’s 17.5% CAGR through 2030 is projected to lift its portion of the power amplifier market size for radio-access infrastructure to almost half by the end of the forecast window. Qorvo documented a 15 °C reduction in junction temperature at identical output power after migrating a 3.5 GHz Doherty stage to GaN-on-SiC, validating cost-of-ownership savings for operators.^{[2]Qorvo, “Qorvo GaN Solutions,” qorvo.com}

Silicon-germanium remained integral to phased-array beamforming cores, whereas bulk CMOS stayed relevant in low-power Bluetooth and Wi-Fi IoT nodes. Research at IMEC on GaN MISHEMT bias stability removed gate-lag barriers that previously capped drain efficiency above 30 GHz, clearing a pathway for GaN proliferation in handset mmWave modules. Emerging GaN-on-diamond substrates promise further thermal headroom, a key enabler for subsequent 6G and X-band radar design-ins.
