FOCUS manufactures since 1993 programmable waveguide impedance tuners from KA-Band (26 - 40 GHz) to F-band (90 - 140 GHz, WR - 8).
All tuners have on - board processor, memora and firmware with interpolation and tuning capability.
FOCUS' waveguide tuners are specified over the corresponding WR waveguide band.
*The model number of each tuner is based on the frequency range and optional on the internal structure:
« xx » = Maximum frequency [GHz]
« yy » = Minimum frequency [0.1GHz]
« zz » = Number of probes or other
