Low voltage high performance mixer FM IF system
Product specification
SA607
AC ELECTRICAL CHARACTERISTICS
TA = 25°C; VCC = +3V, unless otherwise stated. RF frequency = 45MHz + 14.5dBV RF input step-up; IF frequency = 455kHz; R17 = 2.4k; R18
= 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 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 50Ω, but the SA607 input impedance at Pin 18 is 1500Ω. As a result, IF level refers to the actual signal
that enters the SA607 input (Pin 18) which is about 21dB less than the “available power” at the generator.
