20. Input / Output Matching
A few passive external components
combined with the internal T/R switch
circuitry ensures match in both RX and TX
mode. The matching network is shown in
Figure 20.
Component values for various frequencies
are given in Table 1. Component values
for other frequencies can be found using
the configuration software.
