How should we choose between GaN, GaAs, and silicon for RF power amplifiers?

Prioritize GaN when efficiency and thermal headroom drive total cost, especially at higher power or higher frequency. Favor GaAs where mature handset sockets and proven linearity dominate. Use silicon approaches when integration and low cost matter more than peak power density.

What proof points best predict success in 5G massive MIMO power amplification?

Look for wideband linearity support, repeatable thermal performance under real duty cycles, and evidence of multi-band module integration. Ask for field performance data, not only lab curves, and confirm sustained supply for the exact package variants.

What should we check for automotive ClassD audio amplifiers?

Confirm efficiency at typical listening power, idle power behavior, and EMC performance in realistic harness conditions. Validate diagnostics coverage and the qualification approach used for temperature extremes and start-stop voltage dips.

What matters most for Ku and Ka band satellite solid-state power amplifiers?

Demand stable linear power under back-off, predictable thermal behavior at altitude or enclosed gateways, and clear long-availability commitments. Ask how the supplier handles calibration drift and failure analysis for high-value field returns.

How does O-RAN affect power amplifier sourcing decisions?

It increases integration responsibility for the system owner because interoperability and tuning move across vendor boundaries. Favor suppliers with strong application engineering support, clear reference designs, and proven test methods for multi-vendor radio chains.

What supply risks are most common for these components through 2030?

Packaging constraints, specialty substrates, and qualification bottlenecks can be as limiting as wafer supply. Mitigate with second-source design options, lifetime buy planning for stable programs, and early validation of alternates at the module level.
