Wireless Components
Figure 4-9
Above you can see the measurement of the evalboard with a span of 200 MHz.
The evalboard has been optimized for 3 V. The load is about 250+j0
315 MHz.
A tuning-free realization requires a careful design of the components within the
matching network. A simple linear CAE-tool will help to see the influence of
tolerances of matching components.
Suppression of spurious harmonics may require some additional filtering within
the antenna matching circuit. The total spectrum of the 50
can be summarized as:
There should be no problem to achieve compliance with the FCC-radio-
regulations.
