Note 5: IF AGC reference level is defined as being the required voltage applied on pin AGCPWM, and the corresponding receiver
IF gain, to measure 20mV
P-P
at each I/Q differential output when the RF input power is -91dBm. If even for zero volts
applied on pin AGCPWM the I/Q differential outputs are below 20mV
P-P
when the RF input power is -91dBm, then the refer-
ence level is defined as zero volts.
Note 6: In-band IP2 and IP3 are measured with two CW tones at RF input: f
1
= 2339.55MHz, f
2
= 2339.75MHz.
Note 7: Out-of-band IP2 and IP3 are measured with two CW tones at RF input: f
