Note1:
Values have been obtained by applying the test system as Fig.1, with a square wave 99% as modula ion index.
Note2:
The RF emission measu ement has been obtained by connecting the spectrum analyser direc ly to the RX pin 3.
Note3:
By switch on time is meant the time required by the receiver to acquire the declared characteristics from the very moment the
power supply is applied.
Note4:
Values obtained with 10K
