Note1: The 12dB SINAD levels
were plotted using a standard
signalgenerator through a
0.01μF ceramic capacitor at
each point from the RF to the
first IF.
Note2: The AF levels were
measured with an AF voltmeter
when the –73dBm (50μV)
standard signal generator
signal modulated by a 1kHz
modulation frequency and a
3kHz deviation was received
and the AF output was adjusted
to 0.63V/8
Ω
by the AF VR.
