Focus Microwaves' Harmonic Tuners are engineered to enable precise control of impedance at the fundamental and harmonic frequencies (typically f₀, 2f₀, and 3f₀), making them essential for nonlinear device characterization and power amplifier design.

These tuners feature multiple cascaded probes within a single tuner body, allowing independent or simultaneous tuning at multiple frequencies. Their robust design ensures high tuning accuracy, minimal insertion loss, and excellent repeatability across a broad frequency range. Harmonic tuners are the ideal solution for advanced Load Pull measurements where harmonic control is critical.
