M1818

The M is Focus’ flagship proprietary tuner technology. Its performance is unmatched and its capabilities make it the most versatile and popular tuner in the industry. Multi-purpose tuners (L) use two wideband probes, allowing independent control of the amplitude and phase of the reflection factor at two harmonic frequencies simultaneously.

The M technology is widely used for advanced applications like high power/ efficiency RF amplifier design. By controlling the harmonic impedances with an accuracy of >40dB at the source and load, users can generate more robust transistor behavior models and have better insight on how their device performs in all classes of operation.

The M can be used to pre-match impedances at the fundamental and the harmonic frequencies making it ideal for hybrid active systems, reducing significantly the power needed to drive the load of high power devices to |ΓLOAD|≤1. L tuners use two probes and control the fundamental Fo and one harmonic frequency (2Fo or 3Fo).
