Achieving Superior Linearity in RF Systems with HFET Technology – A CML Micro Whitepaper

Modern RF systems demand high data throughput, spectral efficiency, and signal fidelity. HFET technology remains a critical solution for applications where linearity, low distortion, and stable phase response are essential. This whitepaper explores how HFET devices continue to deliver unmatched performance in demanding RF and microwave designs.

Highlights:

• Why linearity matters: Poor amplifier linearity increases error vector magnitude (EVM) and adjacent-channel leakage (ACLR), compromising signal integrity and spectral efficiency.
• HFET advantages: High linearity, stable phase response, and predictable distortion make HFETs ideal for satellite communications, phased-array radar, and high-capacity point-to-point radios.
• CML Micro HFET portfolio: Includes MIMIC linear power amplifiers and discrete HFET transistors, optimized for linearity-critical applications.
• Design confidence: HFET devices provide consistent performance, long-term supply continuity, and simplified system-level integration.
• Replacement challenges: Substituting HFET with alternative technologies often requires significant RF chain redesign, emphasizing the importance of continued HFET availability.
