AC ELECTRICAL CHARACTERISTICS
T
= 3.3k; RF level = –45dBm; FM modulation = 1kHz with 8kHz peak deviation. Audio output with de-emphasis filter and C-message weighted
filter. Test circuit 1. 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.

1. The generator source impedance is 50 , but the SA608 input impedance at Pin 18 is 1500 . As a result, IF level refers to the actual signal
2. By using 45k load across the Quad detector coil, you will have Audio output at 115mV with –42dB distortion.
