Note
P

is measured the input power level when the insertion loss increases more 1 dB than that of linear
range.
Caution When using this IC, a DC coupling capacitor must be externally attached to the I/O pins.
A DC coupling capacitor with a capacitance of 100 pF or lower is recommended when using a
frequency of 0.5 GHz or higher, and one with a capacitance of 1,000 pF is recommended when
using a frequency of less than 0.5 GHz. The ideal value changes depending on the frequency and
bandwidth used, so select a capacitor with a suitable capacitance according to the usage
conditions.
