FUJITSU COMPONENT LIMITED

The waveform above shows the back-and-forth movement as below.
① The object is approaching to FWM7RAZ01 with decreasing the speed.
(approaching)
② The speed gets Zero at the center (stop)
③ The object is receding with increasing the speed to opposite direction. (receding)
The approaching/receding can be judged by Plus/Minus of the phase difference 90 degrees
between I-signal and Q-signal.
In the measurement above Fig.7, since the distance is 50cm of short range, the waveform is the
IF1(I)/IF2(Q) directly observed without the external amplifier.

FCC Radiation Exposure Considerations
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. This equipment should be installed and operated
with minimum distance 20cm between the radiator & your body. If the device
built into a host as a portable usage, the additional RF exposure evaluation
may be required as specified by §2.1091
