(2) External circuits
Since the RF filter that is used in the front stage of this IC features optimization of an attenuation by means of
50-
impedance of input and output, the impedance of the RF port in this IC should be adjusted to 50
in an
application. Examples of the RF filter S
11
whose Z
L
is 50
and whose Z
L
has moved from 50
are shown in
Figure 4-2. Based on the result shown in Figure 4-2, it is assumed that applications with Z
S
= Z
L
= 50
is
optimal.
Employ the following two methods to adjust impedance so that the RF input impedance of 50
can be
recognized when this IC is observed from the front stage.
<1> Match with front stage output’s impedance (parallel C, series L, and series C)
<2> 50-
termination with DC cut
Figure 4-3 shows external circuit configurations for these two methods.
