Low-voltage high performance mixer FM IF system

11. Dynamic characteristics

Table 7. Dynamic characteristics

Tamb = 25 ï°C; VCC = 3 V; unless specified otherwise. RF frequency = 45 MHz + 14.5 dBV RF input step-up.

IF frequency = 455 kHz; R17 = 2.4 kï and R18 = 3.3 kï. RF level = ï45 dBm; FM modulation = 1 kHz with ï±8 kHz peak

deviation. Audio output with de-emphasis filter and C-message weighted filter. Test circuit Figure 19. The parameters listed

below are tested using automatic test equipment to assure consistent electrical characteristics. 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.
