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.

Cryogenic Temperatures

• Fully isolated experiment space for true 4K temperatures during probing
• Cryogenic positioners to provide large travel ranges without warming up the device
• Integrated helium pot for high temperature stability of the device under test
• Fully dry cryogen-free cooler eliminates the need for expensive helium circulation systems
• Rapid cool liquid nitrogen option for faster cool down times

The Low Frequency Tuner (LFT) is a unique product technology using M algorithms for low frequency wideband tuning. Three or more cascaded tuning sections use series transmission cables and parallel rotary capacitors. The length of the cables and number of tuning sections are optimized for maximum tuning range over a given bandwidth. HLFT tuners use 6 tuning sections allowing second harmonic frequency tuning.
