Wireless Components
Figure 3-7
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 Ω at
the transmit frequency.
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 Ω-Output testboard
can be summarized as:
