= +6V, unless otherwise stated. RF frequency = 45MHz + 14.5dBV RF input step–up; IF frequency = 455kHz; R17 = 5.1k; RF
level = –45dBm; FM modulation = 1kHz with +8kHz peak deviation. Audio output with C-message weighted filter and de-emphasis capacitor.
Test circuit Figure 3. The parameters listed below are tested using automatic test equipment to assure consistent electrical characterristics.
The limits do not represent the ultimate performance limits of the device. Use of an optimized RF layout will improve many of the listed
parameters.

NOTE:
1. The generator source impedance is 50
, but the SA615 input impedance at Pin 18 is 1500
. As a result, IF level refers to the actual signal
that enters the SA615 input (Pin 8) which is about 21dB less than the ”available power” at the generator.
