Note 1) With the external circuit shown in the application circuit example.
Note 2) Relative value with OdB as the MOD output level at the time of input of standard
input level (-10dBx) to TXINO.
Note 3) With the C-message filter.
Note 4) Relative value with OdB as the BUFON, BUFOP output level at the time of input of
standard input level (-10dBx) to RXINO.
Note 5) With the external circuit shown in the application circuit example.
Further, the AMP2 gain should be -3.5dB, and hfOD and RXIN should be in loop
connection.

Note 8) The dBx is standardized unit valid for various power supply voltages from 1.9 to
5.5V. If the voltage is 2Y, OdBx should be -5dBm. With the other voltage as X [V],
OdBx -5 } 20 log (X 2) dBml.
