Cautions 1. (Above models)
Measurements of f
RFin
= 820 MHz and f
RFin
= 1489 MHz are upper local
Measurement of f
RFin
= 1900 MHz is lower local
The measured value for IIP

(shown on the right side of the equation) is calculated based on
the logical expression shown below.

This data should be used only as reference values, since the magnitude of VSWR improvement
depends on the parasitic inductance and capacitance of the RF pattern into which external
components inserted and the external components itself.
2. (

PC8112TB only)
While f
IFout
= 130 MHz in other product models, in this product model f
IFout
= 100 MHz (due to
stricter measurement conditions similar to circuits in which characteristics are guaranteed in
the data sheet)
