Application Notes (continued)
2. Input level adjustment for maximum output
You can adjust R in the left circuit diagram
to find the operation point for a maximum out-
put level. For example, since the input level for
a maximum output is
30 dBm when R is open
and the attenuation in the input stage is 20 log
(3k/6.3k)
=
6.4 dB when R is 3 k
. This means
a total gain loss is
6.4 dB as compared with
open mode, hence the input level to get the
maximum output is
23.6 dBm.
Likewise, the attenuation is 12.7 dB for R
=
1 k
and the desired input level becomes 17.3
dBm.

3. Output level adjustment for a maximum output
The maximum output level can be adjusted
by R in the left circuit diagram.
Since the maximum output is
7.5 dBm
when R is open, it is 20 log (20k/30k)
=
3.5
dBm at R
=
20 k
. It is an attenuated value of by
3.4 dB against open mode. Therefore, the maxi-
mum output becomes
11 dBm. Likewise, for R
=
10 k
, attenuation is 6 dB and the maximum
output becomes
13.5 dBm.
